a slut is a girl who lies to everyone and try to get to other guys while having a relationship with you. the defintion of a slut is personal ..... i don't like girl who had alot of men because it shows she can be a unstable factor in a long term relationships.
to be honest.... if i really want a long term relationship with someone , i prefer someone that is virgin or had 1,2,3 boyfriend(s)... but on the otherside a girl who had 20 B-friends ''could'' be totally loyal and comitted.
a slut is someone who pretends to want and have a relationship but is manipulative. naieve. and lies to her surroundings.
''But sometimes when she's giving me head, I can't help but wonder how many penises have been in her mouth. Probably not a healthy thing to think about. heh.''
i usually think this

to
''(unless she cheated on another guy to get with you, in which case you're an idiot for trying to date her). '' i agree
Insecure girls often get manipulated and often lie and cheat on B-friends
''I think it does matter how many guys a girl has slept with.'''
it show she is easy going but also very in touch with sexuality ....
and if she had alot of B-friends or cheated a few years ago this doesn't imply she will do the same now, people change.....
''She *really* seems to know what she’s doing in bed.
Hey man, nothing like getting a BJ from a chick who knows how to hit the underside with her tongue, but it does make you wonder how much dick it required for her to reach that level of professionalism''
for all you know she only had 1 boyfriend that was experienced and she learned alot.... or she read some books or watched some TV shows about sex.
