Is it normal to not have sex effect you much anymore?
So here's the thing: I got a bj today and it took me over 30 minutes to get off. I'm an adult hetero male that has been around the block a few times. I had to think about all kinds of depraved sex shit while I was getting the bj just to get off. She was good at it too.
I've noticed that without teasing or foreplay before-hand, it takes me forever to get off, if I do at all, and that's with sex or oral. With my last ex girlfriend, and my ex before that, half the time there was no foreplay or teasing before-hand, so that made it hard for me to get in the mood and therefore it either took a long time, or I couldn't keep going. There was no real excitement in it. When they'd tease me in public, or outdoors, I'd be hard as a rock and get off within 15 minutes. Even without the teasing or foreplay, if we were outdoors then it was exciting and I was good to go.
Indoors was the problem. Both of them, for the most part, would just want to jump straight into sex with no foreplay or teasing at all. With my last ex, I loved the hell out of her and she was beautiful beyond words, so most of the time I was good to go with her, but when she wanted it a few times a day, I had to dig deep and think of depraved shit once again, but even then it wasn't enough sometimes, since she basically just wanted to jump straight into sex.
When I was young there wasn't a problem at all. I'd get hard at the mere sight of a naked woman and be able to get off easily, but the more I've had sex, and the more crazy shit I've done, it takes more for me now. I'm not old yet either, in my thirties.
So I was wondering if this is normal? For it to take more and more to please a man sexually over time? Or have I just done too much and been with too many women and over-loaded my system?
