do girls feel sexually attracted to men's looks or they are attracted to behavior?
it depends on both but i guess at first everyone pay attention to looks.
as with anything, depends on the girl. some like it, some tolerate it, some hate let's put it this way: i think that some men are physically attractive. someone like leonardo dicaprio for instance. but i have no kind of other attraction toward him (or any other guys, for that matter). but toward women, i am physically, sexually, emotionally, romantically attracted to them (and any other attraction you can think of). i call myself a lesbian because…i am one. don't you see how? i'd never be able to be with a man in the way i could be with a woman. i'm just not built that way. 
if sexual and romantic attraction are essential for you in a relationship, i don't see how you'd be able to be in anything other than a lesbian relationship. if sex is essential for you in a relationship, i don't see how you'd really be able to distinguish panromanticism from homoromanticism, at least where it counts. if you want to base a relationship on romantic attraction, then i suppose that would be an entirely different case. it's up to you, in the end. you need to win the girl over with looks and personality first before you even get a sniff at knowing how much she loves sex. once you have a relationship it will blow you mind how much the average girl needs sex. most of the girls i know want it at least as much as the guys. all teenage girls go true that, it's weird thought!? she looks kind of sleazy and slutty he might have a hand fetish...a sexual attraction to hands. but he might just be a very tactile person...someone who expresses emotions through touch. ok..first of all: love is a word too big to be brought into this discussion. and second: although u found this question to be awkward, once u stay and think for a minute it isn't like that at all. whether u like it or not, sex is part of our life, and it keeps getting more and more important as time goes by. it is true, a few time ago it was kinda ta-bu subject, but now the "sex topic" is as common as...let's say...listening to music! so in an era that promotes and gives a great importance to sex questions like "do girls fantasize about having sex wen they see a hot guy?" are not out of order. on the other hand, it is obvious that he is more experienced in this subject than u are. as a prove we have your "cry for help" here. remember that: a guy will almost never give up an opportunity to have sex! but this doesn't mean your guy is only interested in having sex with you. in this case maybe he would have asked u out already. my advice is for you not to waste any more time by limiting yourself to only simple conversations with him. this could have 2 implications:
1. you fall for him because his "sweet talks" and maybe this is what he is waiting for.
2. this potential relationship evolves into a simple friendship relation, which would be not so good, since you clearly have feelings for him.
so ask him out, or at least make him ask u out! good luck! all men are mamas boys a little, they may not show it, but they all love their moms haha, well, to me, the profession doesn't matter
i base off of personality, and (yes this will sound shallow, but i swear i am not shallow) looks, but only a little bit on looks... Hmm, not sure. It should be something like Holly or Carol, but I am intrigued to know! :)
