Drinking is a negative Smoking is a negative Clubbing is a negative Swearing is a negative
Some of those might not be really bad negatives, but they are still negatives. In other words, not doing those things are all positives. I do (or have done) all those things myself, and there were negative traits about me.
When I hear 'innocent girl,' it typically tells me she's family oriented, goody-two-shoes, and an aspiring mother-type.
Many guys are into that. I myself am not.
While I may not be for the clubbing or bar scene, and while I don't drink or do drugs, I always prefer a more naughty side in a woman, especially if they are sexually open. (And I do find swearing to be quite charming from a woman :P)
well you called yourself boring so? men find boring women boring. innocence is not boring, it is attractive (though not 100% innocent and naive). but as long as the girl has a nice character and other things about her are interesting then its very attractive.
Innocent girls may often be perceived as boring because there's typically nothing very thrilling or daring about them. They're usually very predictable which is what can become boring over time. A lot of innocent girls are also overly concerned with how others perceive them which makes them less likely to take a risk or do something wildly fun and crazy.
