I definitely encourage you to go slow. If he continues to snap w/ you then that is a minor 'win'! I just read this today - some guys just leave bread crumbs for girls to follow and take the lead. If you continue to snap chat regularly (or whatever) back and forth ..... and give it time (perhaps a week?).... then if he hasn't asked you to meet for coffee or a drink or whatever then be bold and ask him! But, don't give in to his request for sex if he goes there (and hopefully he won't right away) let him take a turn and pursue you for a while. Be a little shy or coy. Even though guys act like the only way they are going to really know if they like you and want to keep seeing you is through sex that is wrong. Let him get to know you as a person first. Sounds cliche but it is what will build a relationship if that is what you are going for. If he likes you and asks to have sex and you turn him down he's still going to come back around because he likes you and you've set a boundary which is respectable. Sex straight away usually just gets you sex. Good Luck!
