Most Helpful Guy
Depends on both your situations but from the brief details sounds like asking for a date - Sex that is hard to say - We don't know his views on this, difficult to guess what his intentions are.
Most Helpful Girl
A guy I once asked me to watch a movie with him. Although I was young at that time and clueless what it means, I was also cautious so I declined. Of all his invitations, I only accepted a dinner invitation on a condition that I can bring a friend along, with the purpose of introducing my friend to him. I was helping him find a nice girl but he's so picky. Looking back, I think he likes me.
