Or date a girl who has only slept with one guy, and is also very pretty with a shy personality? Both girls have a sense of humor. The shy one is a lot more naughty once you get to know her, but the other one is naughty whether you know her or not.
I preffer the one that seems more loyal to me which would be the one that does not sleep around. The reputation isn't the issue in and of itself (though one does not get a reputation with out reason, justified or not) but the actions that matter. So from the scenario given the shy girl would seem to be the best bet since for me I preffer relationships. The first girl would be the guys pick if he was only after sex.
"I'm the second girl... But it seems like all the guys want the first one."
Statistically people prefer partners who have a similar sexual history than themselves. People who slept around will want a partner who did the same. People who prefer to focus on a single person will want to have a partner who does the same.
So when people who sleep around prefer other people who sleep around obviously you will witness them regulary. Because those who want comitted relationships will do their thing and it will not be as obvious to you. Selective perception at work here.
Additionally if you don't get approached, you should make yourself approachable. Just existing doesn't grant you the courtesy of guys instantly woeing after you. Eye-contact, smiling, open body-language, not always looking like you are busy and/or being surrounded by a group of friends.
Depends on if sleeping around means unfaithful, if sleeping around means doesn't want to be committed, or if sleeping around means she just couldn't find someone she wanted to date, so she took some people she could fuck instead. If I were single, I'd appreciate a girl who is moderately to very sexually active (if we actually do date, that means better and more frequent sex, as well as more fulfilling sex), but I couldn't get behind a girl who just couldn't stay committed in a relationship. As for the the shy one, I do like that. I like shy people because they don't make me go into large and uncomfortable social situations, and if she is naughty after I get to know her, I can wait for that to show up.
I would choose the slutty one assuming she's no longer like that. I find there different types of sluts. When I think of a girl that sleeps around and nobody knows I have mode respect than ones that talk about it like talking about the weather.
