As for talking during sex, I think it's vital. If you're not comfortable talking to each other expressing needs and wants sexually, then how can you communicate about personal issues to each other? I can certainly understand the embarassment of it, but start small! Tell him what you like and vice versa.
Agreed. I've been down the route of not talking to my partner (now my ex) about sex, and it sucked. He couldn't please me because I was too embarrassed to speak up - he thought our relationship was all about sex, when it wasn't. It led to a lot of problems between us, and it really sucked.
You don't have to talk
during sex, you can talk to him beforehand too. But whenever you decide to do it, as Lunashock said, communication is vital. It's hard to have a loving, stable, healthy relationship without good communication. You two can discuss what works for the both of you, and what you each like, and then go from there.
