Sexual problems in relationship
Hey guys I would appreciate it if you could give me some advice with a problem that me and my girlfriend are having. She's 19 and i'm 20, we've been together for nearly a year and a half. At the beginning of our relationship we used to have great sex on a regular basis, but as the months have passed she seems to have lost interest in sex completely. We have it now no more than once a month. We do really love each other and she has even expressed her desire to get engaged, which i think shows that she's not thinking of leaving me. Another problem is that when we do have sex she is not interested in experimenting at all, its the same thing everytime and she's not interested in any foreplay before and if i try to be different from what she specifically wants, she flat out refuses! Surely sex shouldn't be like this? basically rules are there of what i can and can't do, which is fair enough if it's something extremely different, but for any other couple these things would be normal such as foreplay or a different position. All of this has had an effect on my performance, i don't know whether its lack of sex, performance anxiety or whether she just doesn't turn me on as much anymore but im experiencing problems that iv never had before like sometimes i just can't last at all and sometimes i lose my erection just after we've started! any advice would be great thankyou
