Yes I think it is essential. My bf was away for ten days kept talking about how horny he was and wanted to try new things. It was like hellelujah for me. He got back we had pretty good sex first night. Sex again second night and now havent had sex since. I woke him up yesterday morning gave him a blowy and started ****ing him... coz he wakes up with a hard on everymorning and then he lost it =( We havent had sex since. I feel so unnatractive. I am always keen for sex but we never have it. Its so depressing. =(
