OK, to preface this I would like to state that I already plan to talk to my doctor about this.

I have almost no feeling whatsoever on the head of my penis. For instance, when my wife is giving me a blowjob and swirls her tongue on the head of my penis I don't feel anything. I have a very hard time (no pun intended) maintaining an erection unless I have constant stimulation, and even then it's sometimes hard to get and maintain an erection unless I haven't had sex for about 1-2 weeks. I've had several instances lately where I'm unable to perform and that leaves me feeling very frustrated and disappointed with myself. The most recent time this happened I was able to come by masturbation, but wasn't able to get hard enough for intercourse. Needless to say this is killing my self confidence and enjoyment of sex, because I'm constantly wondering if I'll be able to perform.

Don't get me wrong, I still enjoy sex. Tonight for instance, I took my wife from behind and had a great time...especially since she let me play with her butt. However, I had to play with my self to get me hard enough to enter her. And even then, I wasn't as hard as I would like. I know I can get harder, because I have in the past. So why can't I get that hard regulary?

I have no medical problems that I am aware of except for acid reflux and high chlosterol. (Nexium and Crestor). I'm relatively young (30), but I've had the same problems for as long as I can remember, albeit maybe not as severe. Even when extremely horny I only get semi-hard without direct stimulation. However, I have no problems with getting a morning "woody", which is usually satisfactorally hard.

Anyway, I'm mainly wondering if other guys have a similar problem with feeling in the penis and maintaining an erection. Sorry for the long winded post, but I wanted to give the "whole picture" as it were.
