Soreness

Candice
Does anybody else get sore easily or is it just me? My fiancé and I have been together for almost 4 years and at the beginning sex was always great, we could do it 10 times a day. But now living together I'm lucky if we can do it for 20 mins without getting too tender.. We've tried lube, I've changed birthcontrols with more estrogen.. Have no clue why this happens
