E.S.
It took a long time after my son was born before sex was comfortable/enjoyable again... almost a year. It was also painful/uncomfortable during my pregnancy. I had four problems after my son's birth: vaginal dryness, sharp burning in the vaginal area as though I was having a reaction to the condoms we were using (but I think the walls were just very tender from not being able to produce enough natural lubrication), deep pain sometimes in the bladder/uterus area, and exterior pain at the c-section site.
At the same time, this wasn't entirely new to me because I went through a few years of sexual pain prior as well due to interstitial cystitis. The only thing I can say to help is that at least when it starts to feel good again you'll appreciate it all the more.
