How is sex between you and your partner?

Kayla
Literally just finished with my boyfriend and he's had insecurities with pleasing me. At times it's nice, but when I tell him what to do he gets flustered and embarrassed. I ended up getting stressed and dried up when he almost slipped it in my butt a few times. We argued right after and he says I kept squirming. I don't see this getting any better..
