Is it normal that i don't like to touch my penis?

It's not that I'm asexual, I get erections and all that. But I just hate to touch it, I've never been able to do it for more than a few seconds at a time. I start to have a little seizure, almost, and it's a really disturbing and disorienting feeling, not at all pleasurable. I also don't like the thought of it being touched. Looking at penises also freaks me out, especially when they're ejaculating. It almost makes me want to throw up. Vaginas make me a little sick too, but not as much.

I don't really know what this means. If I see an attractive girl or guy, I think what they'd look like naked and want to have sex with them, but then realize I'd hate actually having sex, it's just the concept. I tried watching a whole porn and thew up.
