Note - I talk about sex quite graphically so don't read if this makes you uncomfortable.
I am a female age 19. I've been sexually active for about 2 years, never really with a regular partner, until I met my boyfriend who i've now been with for a year. My first time was painful and I never really started properly enjoying sex before meeting bf, a lot of my encounters were kind of awkward and not great for me, I never came from sex or foreplay with any of these previous partners and didn't find the sensation of intercourse pleasurable really at all. I have always been very interested in sex and masturbated a lot from a young age and continued to do so when I became sexually active, I fantasised a lot about sex (although not really about anyone I knew), watched porn and was very interested and excited by it.
When I got with my boyfriend we were fairly sexually active from the start and I enjoyed some of it, although I still found some sex painful (long after losing my virginity) and the only real intense pleasure came from oral. Although I still got excited to have sex with him and would initiate it a lot. However, in the recent months of our relationship my libido has dropped quite a bit. A lot of the time I just can't be bothered to have sex, find it hard to be aroused and I often don't enjoy intercourse too much as I find it painful/uncomfortable at times - I rarely find intercourse actually pleasurable, only a few times I have, mostly when im lying on my front and he is thrusting more slowly. Doggy style is generally too painful for me, although on one or two occasions I have enjoyed it. Similarly when he uses his fingers as foreplay I often find the insertion of them painful and I don't get much enjoyment out of being fingered. I find oral sex on me very pleasurable however and I orgasm every time and I sometimes enjoy (and sometimes *** from) clit stimulation with fingers however. I also sometimes find it too intense and a bit painful if its not done exactly how I like it.
All my friends always talk about how much they love sex, especially positions like doggy style which I usually find painful, and I don't understand why I am not enjoying it as much, especially recently. I feel like I never fantasise about sex, rarely masturbate as I don't ever feel horny, just lost interest in sex in general. I haven't talked to my boyfriend about this as I don't want to upset him, but i really want to enjoy sex with him as I love him very much and am very attracted to him. I'm on the contraceptive pill but I have been for years, long before I started having sex, so that shouldn't really be the cause of this.
TLDR/ I have lost interest in sex recently as i find it hard to enjoy sex - i love my boyfriend but I have never really had much pleasure from actual intercourse and actually find it painful on occasions. Why dont I enjoy it like other girls say they do?
