My DH is very well endowed too & at this point in my pregnancy(35wks) it has become very uncomfortable so sex is tapering off abit for us now. I have delivered 2 DDs vaginally before & the 1st time having postpartum sex after 1st DD was born, I was scared to death, we waited 12wks b/c I was so worried about the pain, luckily DH was very understanding & there were other ways to please him & yes he helped out any way he could which did help to loosen things up. It was abit sore after we had sex, & during it burned alittle. After 2nd DD was born we waited barely 6wks & it didn't really hurt at all, I'm not sure why, I was afraid that I was all stretched out by then, but DH said it was still very snug if not more so What we did was use lots of lubrication, astroglide or something like that, it will help dramtically since it is very normal to experience vaginal dryness after delivery due to your hormones. Also DH can loosen things up for you, like you mentioned through mutual masterbation. HTHs
