Welcome
She wasn't very smart and acted like a little kid when we hung out.
Grinding... I am ashamed to say that one of the girls who used me did it to me once, in private, but still. Uh I can see the appeal but I hate it all the same. I've had my experiences with making out and I regret every second. I wish I could have waited to have my first kiss, unfortunately that was stolen from me.
Well my honest opinion is puppy love. Or there isn't any sex. Typically if the guy is getting something from the girl he is giving back. If there isn't any of that it dies, unless the people are made for each other and get around the issue of sex.
As for the other two times I will explain:
Summer of my sophomore year I dated a girl named Amy. Really pale with red/blond hair. I had sent her this forward (we met in speech and she lived down the street from me) which was one of those rate me/what would you do with me? forward. She rated me pretty high and said she would screw me. At the time I thought it was a joke so I laughed it off and a few weeks later we start hanging out. Taking walks and stuff. Well I had started getting a crush on her and she saw an opportunity. I asked her what kissing was like and she walked ahead of me, grabbed me and started eating my face. :/
A week later I asked her out and well she pretty much used me to get some 2nd base satisfaction. She dumped me a month later after she realized I wouldn't put out.
Second was a rebound from that where the girl and I used each other, it was hook up suggestion via a friend. She was desperate, I was desperate so she played off that and would send me stuff.. and you know. Dumped her after he dad caught her giving her guy friend a hand job. She begged so many times and I told her off, deleted her from facebook and that was that.
After those, I had a little reform and I decided to not date. I got myself into the right mindset because I was going against what I had stood for, for so long, because I was caught up in raging hormones. So here I am, haven't kissed a girl in two years, haven't so much as touched a girl, besides a hug, in two years (and slow dancing). I really changed. I am glad I am still a virgin, and I am so glad that I am waiting for the right girl, no matter how long it takes.
So yeah.
