So I'm new to all this [this website that is]...

Anyways, I am 18, and I like both men and women sexually, therefore I am bisexual. But that's not the issue that I'm here to discuss.

I was in a 'serious' relationship for about 3.5 years, beginning in 2004 and ending in early 2008. I was with a girl at that time, and when we tried sex (which we did probably 10-20 times per month) it worked I suppose the way it is supposed to. However, when she wanted me to do her from (FROM not IN, there's a difference) the behind, my penis wasn't 'strong' or 'hard' enough to actually penetrate her, which eventually caused both of us to have sexual tensions in our relationship.

Anyways, I've been hooking up with other people, including guys, for the first time, and I realized that I cannot recall ever getting a fully hard erection. I never knew what a 'hard-on' truly was until I felt up other guys' rock-hard penises. When I felt the erect penis' of all of these guys, there were seriously hard as rocks, without exaggeration, presumably the way mine should function. Anyways, I wanted to be the giver in an anal penetrative sexual act, and my penis could not get hard enough to actually penetrate. [Some may argue that the penis is not designed to enter the ass, but even so I should be able to get hard enough to penetrate it.]

When I am as hard as possible, my penis is still pretty flexible/bendable, and can bend to a greater degree than it should when it is hard.

My question is: Do I seriously have erectile dysfunction at such an early age (was I born with it??)? [I don't even recall masturbating when I was younger and getting as hard as I should be]

How do I solve this issue? If one of the replies asks me to visit a doctor, how should I approach getting onto this topic, as it is obviously something embarrassing to discuss.
