Guys,
I've been married for 2 years. I was a virgin till my wedding night so I have only been with my husband and he only with me. Now I love him so much but I think as much as sex is great we just have sex the same 3 ways me on top, him on top and on our sides facing each other. 
We've kind of tried other stuff but idk we both don't really know what to do. I need help!
