Females don't want to admit this about themselves, but this shit is true.
Guys can be dogs, and we don't need a reason to cheat. If you look good, we'll fuck. It's not an excuse,and doesn't make us any better, but that's what it is.
But girls, there is a thought process that goes into it.
I am currently having this situation myself.
My good friend has an attractive coworker. A while back he brought her out one night to hang out, and we hit it off. She had a bf at the time, so I made no moves, but me, her, my friend, and a few others were hanging out together on a regular basis. She eventually tells me she likes me, and I say the same, but she kept giving me the run around on actually making things happen. She'd flake out on meeting one on one, and just play these silly games.
I finally had enough, and we stopped hanging out for a few months (because she broke her leg) and i found a girlfriend in that time.
I hung out with this girl (in our old group) for the first time in a while last weekend, and this chick was all over my dick. I actually felt embarrassed for her. She tried to make out with me, and tried to make me jealous by saying 'well i guess i have to fuck some other guy tonight since you won't do it'.
It rained that night, and i was the only one who brought an umbrella....she thought i was going to give her mine....lol...It was sad seeing an attractive girl reduce herself to that level.
I'm not even salty about the whole thing anymore. But i have female friends, and i treat those female friends just like i treat any of my dude friends. Im not giving up my umbrella for my dude, and wont give it up for my dudette either.
