Most Helpful Guy
If you wanna fuck this guy, then go.
If not, then don't.
You can probably have some fun for a while, but don't count on anything long term.
He probably can't or won't give you what you want down the line, and people WILL look at you weirdly if you decide to take it further and 'go public' if you actually decide on a relationship.
Think about what you want, and go from there.
If you have any doubts whatsoever about having sex with this guy, just end it before it starts. He's not hanging around you for your chess skills.1
