Tickling games to play with boyfriend?

He says that he loves to tickle me because he loves seeing me laugh and being happy. So, he wants me to ask about some tickling games that we can play. None with , because we don't want to do that. :) He says that I'm the most ticklish person he's ever met, and I REALLY want him to keep tickling me as much as he does, because I love it. <3 :)
