The obvious answer is that he only calls you at 2am...
Otherwise, look at your interactions. Does he take you out for diner? Hold your hand in public? Have you met any of his friends? Does he spend the night?
There are always signs of a relationship forming or just a booty call.
There is only one way to tell if a guy only wants you for sex. If the guy always ask you to have sex and never ants to do anything else means he is using you.
If he completely stopped talking to you after the sex, or if he only comes around when he wants sex, then he did/is just using you.
Check and see if he is breathing. If so, then yes.
sex
Then you need to get out of the relationship. You NEVER want a guy who only WANTS you for sex. AND I do mean it. You are worth way more then that.
if the guy enjoys talking to you, and just hanging out with you without having tons of intamacy and physical contact then u can tell he wants you for more than just sex. if the guy contantly asks you to hook up or whatever he definitely just wants you for sex
All hetero guys see all females as potential sex partners, so assume he does, unless you are a relative or a vast age difference.
he only wants you as a best friend so that he can get close to you and "accidentally" have sex with you.
just ask,we guys love oral sex
If he's always hanging around without sex in the picture.
When the girl is only interested in sexual things, this is a sign. If she wants to talk about nothing but sex, this is another sign. She may also sexually confuse him.
Just tell the guy that you are not ready, and if he really loves you and wants to be with u then he will unnderstand and he will wait till u are ready. If he dont want to wait then its not meant to be, and he only wants u 4 sex.
