Well there are many ways to tell if the lad had feelings for ups .
- he always leans towards you when he speaks
- his pupils dilate when he looks at you
- he looks for things in common
- he looks for reasons to get into contact with you
- he may seem protective of you
- he asks about you to your other mates
- he asks you out
most liely if he wants to have sex with you XD sorry I don't know all I know is like 95 percent of guys here are douche bags (not on this site I mean where I live)
Really. Most people I know are the opposite; women would ask for sex for men they like, or be flirty, and men treat women nicely as if they're that special.
