What do you think of this scenario with my boyfriend?

Hunny, he just wants to touch you, this is something normal in a healthy relationship. However, it is true also that some moments are just not appropriate. It is easy to mess up when you don't take the right time. But don't get that irritated, he is just showing his affection. I am sure that if that annoys you that much, he will be able to get the message through. Just, I guess, you have to define your moods for him - so that he will be able to decide on his own whether the situation is appropriate or not.
