I'm loving this thread!
My vagina and I were not on speaking terms for a long time. But I've almost forgiven her at this point.
I had an episiotomy with DS1, and I never healed right. My perineum was very, very painful until DS1 was about 8 months old. I think I was stitched up too tight, which made sex uncomfortable even though the rest of my vagina was a little looser (which I actually appreciated, since I was almost "too tight" before having kids).
DS2 was born unassisted; relatively short labor, and brief but intense pushing phase. I thought my vagina came out of it unscathed, but 5 days pp I gathered the courage to look into a mirror, and I had actually torn pretty badly. It had already begun to heal, so I let nature do her work, and that tear healed within a few weeks with no discomfort whatsoever. We had sex at 8 weeks pp and I only had a little pain. My vaginal opening is kind of funny-shaped now, since the torn edges weren't perfectly aligned, but I can deal with it.
The real shocker came when I discovered at 2 months pp that, at 22 years old, I had a prolapsed uterus and cystocele! That killed me. I felt like my body had completely failed me. I didn't have enough pelvic strength to have an orgasm until I was several months pp. Thank God it's gotten better as time has gone on, and I don't experience incontinence, but just knowing that my cervix is hanging out just a few inches into my vagina destroys my confidence. To be so young, and in good shape, only 2 babies, easy births . . . gah. Turns out I was predisposed to prolapse; I'm pretty sure my mother and grandmother had it (both had incontinence problems after having children), and I already had a tipped uterus, and women with reddish hair tend to be affected most by it. I've accepted the reality of what condition my vagina is in, but I still wish I could just get a new one!
Oh, and to whoever said "frankenpussy" -
