June moms having sex? Still hurting too bad

I'm still too sensitive/tender at the lower end of the opening. Feels like skin was stretched over hole when she sewed me up...or sewed me up too tight! Dr told me to have lots of sex (didn't even ask) said it would hurt but it hurts SO bad. Weve used plenty of lube. We've tried twice in one week at 6 weeks. Now 7 weeks and hoping it won't take too much longer to heal:-/ anyone else in the same boat?
