My daughter is almost 4. That has had literally zero impact on my sex drive. I don't watch porn and think "that's somebody else's daughter". I think "that's a grown ass woman who made a conscious decision to get paid to have sex on camera". When my daughter gets old enough to start dating, I hope that we raise her to be smart and know her own self worth. I was a young man once, and there was only one thing on my mind, and I wasted much time and energy try to get laid. I also have a 6 year old son, and I hope to instill some core values and a general respect for women that nobody really bothered to talk to me about as a young man.
I think as my daughter gets older, I won't be able to find girls around her age attractive anymore. It's already happening. I'm only 35, but when I look at college girls, they seem like little kids to me now. I'm married and not looking, but if I were single I wouldn't consider dating anyone under 25-26. My friend (34) just recently got divorced, and has been sleeping with a 22 year old college student. I "hung out" with them once, and she is so immature it's painful to be around her. No judgement, I was 22 once and I'm sure I acted like it... but I also wasn't dating a 35 year old.
Funny story; Last fall, when that friend's divorce was final, a group of his close friends went out for a "divorce party", which I guess is becoming as big of a thing as bachelor parties. Anyway, we went to a strip club. Personally, I was well behaved and chose to spend my money on cocktails rather than trips to the VIP room ($200 a pop, which some of the guys in our group did!!!). I got talking to this girl who was trying to get me to go to the VIP room, since my buddies were doing it. I told her she should go look for other guys, I'm not going to be spending that kind of money. But we talked a little more, and she told me that she was born in 1998!!!!!! 19-****ING-98!!!!! That's the year I got my driver's license!! It was at that point I realized that I'm no longer in the same rough age bracket as strippers, and am getting closer to "dirty old man" territory. I rarely find myself in such establishments, but it was just a weird experience!
