So about a little under a month ago I took my friend's virginity. We've had about 3/4 sex sessions since then. The first time he couldn't cum from blowjobs or vaginal sex w/a condom. I knew it was his first time and so I told him not to worry, he's probably nervous and also might just be used to masturbating with a really tight grip or too quickly, but that could be changed if he "retrained" his dick with a different masturbation style. He slept over and the next morning we tried again and I suggested we try doggy (even though I can't orgasm from doggy) bc it might be the position best conducive for his orgasm. It took a little while but he came in this position and he was really happy. The next time I saw him we were drunk at his house with his roommates so we snuck into the basement and I tried to give him a blowjob again. It took such a long time and my mouth was sore after but I managed to make him cum.
The second time he came over he said he hadn't masturbated since he last saw me so that he could cum while looking into my eyes (what a cutie lol). I told him let's not use a condom this time (this is really risky for me because I have a protein deficiency and I cannot use birth control or I could potentially die) and he came rather quickly (don't worry he pulled out). I gave him another blowjob after a little while and it was still rather tedious but he managed to cum. He feels really bad that I get so tuckered out trying to please him and I don't really mind right now because we're in the honeymoon phase and I'll pretty much go above and beyond for him but I know that after a while I will probably get tired of putting forth such an effort because my mouth and throat are so sore afterwards. It really saddens me because I usually love to give blowjobs and I really want to please him.
The last time he slept over was yesterday and we were particularly unsuccessful. I was on my period so I wasn't super keen on having him over but I missed him a lot and he really wanted to see me so I told him **** it just come over. At first we weren't going to do anything sexual other than make out and maybe a blowjob, but he said he said he didn't care if I was on my period. Even though I love period sex, because its when I'm the most horny, I'm extremely self conscious about it because my most recent ex was really disgusted by my period. So we started ****ing w/a condom missionary position and I noticed he was doing a lot better (the first time he had trouble with rhythm and keeping his dick inside me) but for some reason I started to get dry and finding it difficult to orgasm? I mean I orgasm pretty frequently during sex (every 5 mins) so I'm usually drenched except for when I'm incredibly dehydrated. I was rather sweaty since it takes my friend such a long time to cum so I'm just going to assume I was dehydrated and sort of self conscious because I was on my period. But anyway, it was still taking a while so I said lets do doggy bc you seem to do better in that position. We started doing doggy and I think he may have hit my cervix? He has the biggest dick of anyone I've slept with so I've never had anyone hit my cervix before. I don't know if me being dry had anything to do with it. But whatever it was that happened hurt both of us a lot. I think me more than him because my vagina is still sore. Anyway after that we stopped because of the pain and we just chilled and talked. After a bit I tried giving him a blowjob and like the first time I couldn't get him to cum. He started feeling really bad because he had hurt me and he can't seem to cum for me. I tried my best to reassure him, that I don't mind and I'm going to help him figure this out and I'm still insanely attracted to him. He slept over and I woke up to his dick grinding against me. I was still really sore so I gave him a morning blowjob instead. This blowjob, although still one of the most difficult blowjobs I've ever given, was not as difficult as the other few times and I made him cum on my own. After this I inspected his dick. He is circumcised and I remembered my first boyfriend was circumcised and would also take a little longer to cum, although not nearly as long as my friend. I noticed my friend no longer had his frenulum which my ex told me is the most sensitive part of a dick.
I'm wondering if my friend's trouble is related to more than just "death grip" while masturbating. I feel really bad that sex is so hard for him and I want him to be able to enjoy himself with me and whoever else he ends up with. Even though he's rather extroverted, super ****ing funny and really handsome he's extremely self conscious about women because he's a little chubby and couldn't find a romantic or sexual partner for so long (we're both 25). This sort of baffles me because he's a really great guy, witty as **** and a literal genius. I've seen other not nearly as exceptional boys with similar body types get with some hot chicks. Please help because this guy is one of the best guys I've ever met and he's lead a particularly sad and tragic life and I really want him to be happy. I also don't know if I should tell him about his situation. When I told him he didn't have a frenulum he didn't even know what it was or that he was supposed to have one. From what I've read most men w/out their frenulum are devastated by this and claim they have no hope of having good sex and that most girls they end up sleeping with are extremely disappointed and end up feeling extremely emasculated. My friend however seems to be okay if we're not using a condom, but like I mentioned earlier I can't take birth control so I don't know if that's an option for me.
PLEASE NOTE: I do NOT care if he can't cum from sexual intercourse. I don't think sex needs to always be about orgasms. However it is really important to him that he be able to cum inside me while looking into my eyes. Yes I admit this would be nice to have, but I really could not care less if it doesn't happen. I just want to give him what he wants. I was harassed by someone on another forum claiming that I am an insensitive narcissist incapable on empathy. So I just need it to be clear so no one misinterprets my intentions.
tl;dr: My new FWB and possible future bf, who is circumcised and no longer has his frenulum, has trouble reaching orgasm from intercourse. He's already self conscious and has had a really tragic life as it is and I'm worried that this could crush him. PLEASE HELP!!!
