Do you think a vv shy guy would be w/ someone very social?

I think for some people who are shy then a more outgoing companion may compliment them and be what they need to help bring them out of themselves, so long as they are not neglected while there outgoing partner chats to everyone else, in which case they may feel abandoned or jealous even. They need to be included but perhaps for the extroverted one to take the lead.

if that someone very social is always paying attention to him and keeping him their first priority only then will he probably with them

I guess it all as well depends then :)

Depends on the guy.

there's no yes or no on that... it varies with every other shy guy :D

I'm shy and I would.
