My sex life is great except for one thing: after I orgasm I get really depressed. After I ejaculate I feel like sex is disgusting and I have done a gross thing. This feeling usually only lasts for about ten minutes, but it is so unpleasant that it makes me really dread the end of sex.
It is not unusual to have a slight letdown after the highs of sexual intercourse and orgasm. You also have some guilt about your sexual urges. It is a natural part of life, so accept it and enjoy it.
Sounds like you might not be totally comfortable about actions in the bedroom. In my experience, when I am horny, reality kind of fades away. So usually if I am in anyway regretful of my action in the beginning, they situation usually becomes more aware to me in the end.
