what do you think of this guy?

when this guy calls me we talk for more then 2 hours ( we talked for 3 and 4 hours straight ) but we don't talk on the phone everyday like twice or three time every 2 or 3 weeks. he text me almost everyday for hours.i heard that guys do that only to get into a girl 's pants.he is not a virgin, i am.he knows that i am saving myself and that i won't have sex even if i have a bf. we been talking for months now. he talks really normal to me. he isn't really the sweetest guy ever but he is okay. what do you think about a guy like him ?i have a problem trusting ppl. he is really street smart.how can i know if he wants to get into my pants ? i try to ask him but he say that he doesn't want to have sex with me.

when i ask him why he talks to me, he say cuz he likes to keep contact with ppl. how can i know for sure ?
