It's nice to know I'm not alone here. I am 39 years old and was once very sexual - like a guy. I had many partners throughout my life and always enjoyed sex. I used to be told by men that I exuded sexuality, I was at times told I was insatiable - yeah, I could never get enough. I loved to initiate sex and to drive men crazy. I craved it, used to masturbate all the time, and at times felt like I may even have a problem with it (possibly an addiction to it - or men). Basically, I was just full of lust. Constantly. If I wasn't getting it, I was fantasizing about it and masturbating. Until a couple years ago... when I began noticing that I didn't really have the urge to masturbate much anymore. And if I did, my orgasms weren't as intense. Then I stopped lusting after guys. Like if I saw a good looking guy, I'd just observe (like whatever) and move on. Where as in the past, if I saw a good looking guy, I might even approach him! Or at least give him a good look/lust. I am presently in a relationship with a man who is in his mid-20s - yes, he is in his prime. He is very smart, good-looking, and loving. For the most part, we get along quite well. And I am very attracted to him. However, I no longer have a sex drive and when we do have sex, I don't feel much pleasure. Penetration used to feel so good it gave me chills, now I feel nothing. I know it's not him, it's definitely me. It's like I'm an entirely different person than I used to be and it really freaks me out at times when I think about it too much. I feel like a part of me has died and it makes me depressed. My boyfriend has asked me why I never initiate sex (I try to as much as I can, just to please him but I'm really not very interested much of the time) and the worst part is that I just don't produce much lubrication anymore - which makes sex painful for me now (which is also why I don't want to initiate - now I'm also afraid of the pain). I have discussed some of this with my boyfriend and lucky for me, he is very understanding. But he doesn't realize the extent of my issue(s) - not that he should. When I had a voracious sex drive, I could have never understood this. I have talked to several doctors about this and they're just like - "well, you're getting older" or "I hear these complaints quite often" or "it's a mental issue" (which I know in my case it is definitely NOT - I have no hang ups about sex and I'm in a good relationship). But none offer any SOLUTION! What can I do about this? Just accept that a part of me is dead and will never come back? Not one doctor has offered me any good advice. I'm sad and at a loss... I feel like that sexy woman I once was is gone forever =...( I do not want to lose my boyfriend over this one day.
