FTP 1/2 TT raised on flop

[McRoNiX]

1st session ever on FTP. Had villain as 24/18 over like 30 hands and had no other reads so was lost here. Do we just fold situations like this against unknowns and wait for better reads/spots?

Also what are your oppinions on 3betting an unknown oop? I can find arguments for and against, the against being spots like this, lol.
