So, as the title says, I was a nice guy for like a good 18 years of my life. I have the good guy face, the calm smile...everything. But it didn't help me getting laid. BUT, as soon as I started to show more aggression, panties were dropped. For example, a female friend of mine knows me for around 6 years. No sexual contact whatsoever till then. One day, we were joking around, and i just start to grab her ass in a very strong manner (which was super close to sexual assault but I guess she let it slide since I am, as I said, a really tame looking guy - and she said that her ass was her biggest asset so I had to check it), suddenly I see her eyes light up and she gets a little sound out of her mouth with a huge smile on her face and it escalated from that point. Rough sex was the result. Worked for me with like at least five other girls.

How are your experiences with that? I am especially asking the nice guys out there.

edit: I'm Asian. If that is somehow relevant.
