Ok I'll bite, I am. I'm 27.
I think I have a very different attitude than most on here. I am not interested in a one night stand or just screwing around. I've had more than my fair share of girls throwing themselves at me for that. And the girls I have had relationships with were the "nice girls" who want to wait until their married. I don't date slutty girls and I'm not interested in hurting any girl's feelings by just kicking them to the curb after sleeping with them.
I don't look at it as a big deal. I look incredibly young for my age and I'm pretty good looking so I feel like if I ever do want to "enjoy" that aspect of my life I can at a later date and still date much younger girls. For most guys once they hit their late 20s they begin to age and I guess they feel rushed to "enjoy" younger girls as much as possible before their selection is limited to "aged" women. I own a business that may become successful very soon and I will then have the freedom to spend with the other sex, but I would rather work and focus on that right now. The reward will be much great to be rich and being able to date attractive girls than just do what most do (screw everything that breathes while you're young). But otherwise, I'm happy where I'm at.
Ok, make fun.
