Hope this is OK to ask on here, I never know what is allowed when it comes to sex etc but i don't know what else to do as it's a bit embarrassing!
After some initial sex issues with my new DP we have got over them but now have an issue that if I go on top, it just doesn't seem to work. I never really did it with my husband as he was always wanting to be in control so did most of the hard work, so it might be that I am doing something wrong. Anyway, I get on top and it goes in but doesn't stay in and we keep having to stop as it just keeps coming out 
He is now worrying that he is too small for it and he is nervous about things like that anyway so I just want to be able to reassure him and also be able to take on some more control in bed.
Anybody know what I am doing wrong
