I just started University about two months ago, and this roughly coincided with me discovering game. Until a week ago, I was a virgin, but since then I've managed to sleep with five girls, and K closed about 15. While this sounds like success, I have also gotten a reputation as, in short, a manslut. Im not very good looking, usually quite scruffily dressed, useless at sport so I fulfill none of the criteria you'd generally think of for a guy at university who gets laid all the time.
Basically, I think the reason I have success is that while about 85% of the time I'm a complete AFC, when i get into state I become incredibly attractive for reasons I still havent worked out.

But my problem is, because of this reputation, and the fact that I have a reputation as being a tad crazy (I am manic depressive, which might explain some things and ), girls who get with me tend to get teased/ribbed mercilessly. I made out with a very attractive/popular girl two years ahead of me the other week and went back with her (although didnt F Close) and she hasnt heard the end of it. Two other girls I know that I slept with have both told me a similar story, and this inhibits me from getting anything from girls I know

Of course, my problem, an incredibly amateur and stupid mistake in retrospect was that in the excitement of suddenly getting laid, I tended to brag to everyone who would listen about my exploits. Which made many people think I was just some kind of sex obsessed perv with a one track mind (not an unfair accusation in some ways. And this is a reputation I have among virtually everyone.

How do I go about dealing with this? my thoughts have been that I should try and show a more demure, sensible side to my personality, and gain recognition through other means (i'm a very good public speaker, and a published writer, so I was thinking getting involved in these things University wide on a larger scale, which gets my name known for non whorish reasons.)
And not suprisingly, none of the girls I've gotten with have wanted a day 2 (even though one of them happened to say that she actually really liked me to our good mutual friend)
