Signs he wants to be more than friends?

It's awesome that you're noticing all of this great body language because I think he's totally into you. But since you're shy about asking him about, wait for him to do it because it might happen in a couple of weeks. The only thing is, don't get physical too early because of the girls. They look up to you and if mommy starts shagging their gymnastics coach and then gets her heart broken, practice is going to turn into a whole lot of awkwardness. Good luck!
