How fast can a girl tell if she wants to sleep with a guy or loves a guy?

This is a very interesting question.

From personal experience....

I think a girl can tell if she wants to sleep with a guy, after the first date. Although women know quite early on if they want to jump into bed with them, it often takes some time before she will actually sleep with him. Personally, I wouldn't sleep with a guy before I get an emotional response from him. Women need good conversation, honesty, and have to feel that romantic connection with a guy before jumping in the sac.

How long before a girl can tell if she loves you?? I think that depends on the relationship. I think from personal experience that love isn't at first sight, but I can definitely tell after a couple dates if the potential for love is there (in the future).

How much time does she need to read him??

Wow....i don't think guys are easy to read at all!! Thats something that takes some time. Although, women can always tell when something's wrong, or if a guy is lying to her. Women have this intuition about men...and they're usually right about something right away! I think that if you have a real connection with a girl, it's easy for you both to read each other. I feel we send of an energy to one another, and when you make that connection emotionally and physically, it makes understanding each other more easier.

sleep = physical attraction = sweet f all time. I know the instant I meet a dude if I find him physically attractive. but sometimes if I get the vibe, that the guy isn't just arrogant - like has a dece life, dece head on his shoulders, optimistic, witty - I'm like sh!t there could be more. when this happens, I don't f the guy. I wait and I get to know him. love takes time.

but the 'vibe' or how relaxed and happy I feel around him definitely contributes to whether I think there is a possible future (kids, house, dog ...) for a long term love relationship. if she smiles a lot, you're off to a good start.

sleep = in a click BUT if potential - we wait.

loves = if first off comfort + healthy dose of butterflies vibe good then you're on your way (girls like fairytales so we make sh!t up and convince ourselves that it was love at first sight, we just forgot about the 3 other times when we first saw you :P)

read = depends on her body language reading abilities. and how open you are w each other, usually after 3 dates I know for sure if he is date or fark material.

I think with me, I can usually tell on loving someone after I get to know the guys personality, their actions and what they like and if we get along. Typically within the first day of meeting, depending how long I have talked to him. How much I really am comfortable with him too. And usually if I have some idea that he has feelings back, or I get nervous with saying anything. Sleeping with him, I guess for me, if I get along with him as HIM in general, not to sound sluttish but when I know him more than the neighbor guy, I believe sleeping with him would come along soon. Reading him usually comes with how long you spend with her. Body language says a lot, but can be very confusing, so it also depends where things lead.
