Well ours was better right after... simply because sometimes I was nervous about BC failure or something. And with the freedom of no holds barred sex, we probably had more of it once he was healed and we could.
But otherwise, medically, it should remain the same.
We're at the in between stage. He's had the procedure but we still have to use condoms. (That actually ends on his birthday. Coincidentally.) No difference for that. Once the two weeks of no activity was up, he didn't experience pain or anything.
