Peeing after sex bad?!

Whitney • I am 25 years old. I ttc with my first husband for 2 years and had no luck at all. Now my fiance and I are ttc. Haven't had any luck so I went to see a Dr about a year ago. First I was told I had blockage in both tubes. Had laparoscopic surgery which open
I have a tendency to pee right after sex because I can't stand to feel the cum just ooze out. Since I'm ttc is this a bad thing? Should I just stick a towel between my legs and suck it up for a while? I mean I know it doesn't all come out when I pee but will leaving it all "in there" improve my chances of conceiving? Thoughts and opinions greatly appreciated! Thanks!!
