Is normal to do this?

Okay, I'm a pretty confident person, and whenever I see a couple making out or having sex, I get the urge to dive into them and tackle them. Most of the time, I actually do it! It's so much fun! Sometimes the couple are complete strangers as well.

I often get my own girlfriend to pretend to have sex with a blow up doll, so I can dive into them as well. I would rather be doing that than actually having sex. I find sex incredibly boring, to be honest.

My friend gets really mad at me for this, I know it's a little weird, but it's just SO MUCH FUN!
