I'm 26 weeks pregnant and trying to have with my husband has become a nightmare?

If you are pregnant and is that painful, then stop doing it. You may be carrying one or both of the babies lower than usual.You hubby won't die without for a few extra months. You can always find other ways to pleasure him. Your doc needs a kick in the to teach him some sensitivity. Don't "try" to talk to him about it; demand to talk to him about it and don't let him brush you off. That is what you are paying him for.
