I woukd find it very difficult too. Especially if start to tease just by putting head of cock at your entrance. Would be sk hard not to go all the way. Maybe keep panties on and just grind on his shaft.We're not engaging vaginal penetrative sex during my pregnancy. We've had a high risk history, I am not currently high risk, but our emotions are high, but so are my hormones. I am trying to hard to respect my husbands wishes, but it's difficult!
