There's a point in time when having a barely 20 something year old check you out that makes a girl feel dirty... And not in the fun way you are thinking!
It goes without saying that guys probably don't think like that when a young 20 year old female checks them out but for me... I just feel weird.
If I notice a much younger guy staring, I'll look away and try and walk fast in the opposite direction. I feel like it is inappropriate for them to look at me and for me to look back, even when I do like the attention. It's a strange feeling and it makes me wonder about those women out there having relationships with teenagers. How do they do that?! There is just some things a man can do a hell of a lot better than a boy!
When a guy dates a younger girl, he's rewarded with a slap on the back, a punch in the shoulder and a loud "way to go" but if I walked into a room with a guy that looked half my age, I'd get angry stares of disbelief! Well, at least from the women... the guys would probably be thinking something along the lines of... he must have a big cock. In all honesty, that would probably be the only reason I would be dating a 20 something kid because I highly doubt it would be for intellectual conversations.
I'm not as old as I now sound but I have to say, when I entered my 30's my desires changed. You don't think about those young boys surrounding you, you think about the man that knows his way around your body and mind... It's called mind-blowing for a reason!
