it really just depends on what he's asking you. if he's asking about your sex life, or if you'd do certain things if or if not in a relationship, then he could be interested because he might like you and might want to do certain things with you.
What else? Hmm...
Well, if he asked "If I suddenly asked you for a hand job, would you give me one, regardless if we are in a relationship or not?"
If he asked you that, then chances are he's interested...but only in a sexual way. But then again, if he's a sweet guy whom you've known for a long time, such as half a year to many longer, then he might like you.
If he gives you compliments, though not on a regular basis, calling you sweety, honey, or simply giving you nicknames, then yeah, he might like you.
When he starts asking personal questions.
If the questions are about you every time themn it might annoy him especially if the questions are asking him if he likes you.
if that friend is a true friend she/he will do it but if they hesitate they might be shy about asking him. of course they have to make sure not to blurt out that ur asking.
Just asking a guy usually works
Try asking him out!
When a that guy says the question with a smirk and he is jealous of the guy he is asking for.
He wants you.
if youre asking this question then you don't need to know.
It means he is asking if you and your friend are friends to each other. The answer would be "yes". Or He could be asking if you are a friend to him. The answer is either "yes" or "no" depending on what you feel.
It depends on whether you ask him stupid ambiguous questions.
Ask him about something he loves
This is coming from a guy just ask him if you like him or have a friend to do it for you But do it by yourself because I don't like their friends asking for them
