Whisper in his ear, grab his butt, depends on what he likes.
"OH yes". Really you don't need to say anything but moan and groan in pleasure. That would be enough signals for me.
wear it maybe he willl like it if it pops?
It's not that uncommon, but If you don't want to then he should respect that.
yes its normal for people to do that
Yes that sounds like a good idea!
Yes, it's fine.
hug him, and do whatever feels natural after that.
feel his abbs! :)
YES, LET HIM!!!! guys are AH-MAZING AT THAT
If you want him to do it. Or if your comfortable with it let him do it. Really it all depends on what type of girl you are. Also make the right choice.
pull out and slap him
Just the act of making out should turn him on. Kiss him and caress him.
