For the past several years I've had issues with achieving orgasm through intercourse. I have regularly dated women with healthy sex drives (wanting sex every day or every other day), but have had issues with performance anxiety and concentration. I have no issues with orgasming through manual stimulation, and regularly watch porn and masturbate, but when it comes to having sex something happens that makes it very difficult. Having researched the issue online, I discovered that I likely have what is referred to as Sexual Attention Deficit Diorder, or SADD, which is often the result of too much masturbation / porn. Has anyone else had experience with this problem? It isn't that I can't achieve orgasm; most of the time I do. The issue presents itself as loss of erection during sex from a combination of lack of interest and anxiety at the thought of not achieving orgasm. Also, even if during the first few minutes I seem poised to ejaculate, I become very anxious at the prospect of climaxing before my partner, and it turns me off. By the time she has been satisfied, I have lost interest and my erection. What usually occurs is some break in between, and then a sexual encounter for the sole purpose of orgasm, which is usually achieved shortly after penetration. If not, then oral sex will always allow me to achieve orgasm. It's as if sex has become a job for me: 1) I have to make sure she has a good time, and orgasms at least once 2) I have to make her feel good about herself by giving her the impression that I'm having a good time, which means I need to climax. I know the orgasm isn't everything, but when a man doesn't climax during sex it makes it much less emotionally satisfying for both partners. I have tried to lay off porn before, but the irony is that I have a very very high sex drive, and often have to masturbate two or three times just to be able to focus on other things. If my partner were around every time I got really horny (usually mid day) then I think things would be different. But often times when we're together (during the evenings), I have already masturbated or am simply not very horny. I hate the fact that has become a point of stress for me. Also, if there is any indication that the girl isn't that into sex, I immediately lose interest and erection (save for the few times when I am having sex because of a strong need to orgasm). It is as if I cannot enjoy myself unless she is enjoying herself.
