My boyfriends really into PDA infront of my friends and family but im not?

I am like you. I hate PDA in public at all. Well i mean holding hands ounce in a while but no more. If you really like the guy then just flat out tell him how you feel..he has to understand, but don't ignore the pda, he must need a little more then what you are offering so give it to him when you aren't in front of the family.
