Need input HeLp!!

Me and my boyfriend have sex everyday 2 or 3 times a day I'm almost 12 weeks pregnant and the sex is amazing I've never been one to give blow jobs nor be on top riding him but it feels so amazing since I've gotten pregnant. I want to start being more adventurous but don't know how to come about it to him! Can you guys help and where are so crazy places you've had sex!
