So I read somewhere that one dose of prostaglandin gel (like Cervadil) is roughly equivalent to three "doses" of semen "applied" within 1/2 hour.
Since I've had a c/s I know I have to avoid prosaglandin induction like the plague, but does that mean I should also be avoiding sex? Of course we're not going to do it 3x in 1/2 hour, but even once would be like 1/3 dose of the prostaglandin gel. I've been having lots of bh's and losing my mucous plug so I'm thinking it won't take much to kick labor off... but is it a big deal if the natural prostaglandins from dh kick it off?
With my first I was induced with just Cervadil so I might be one of those people who are particularly sensitive to prostaglandins. I don't really understand why the risk of rupture goes up so much when prostaglandins are used, but if semen and Cervadil are pretty much the same (besides potency) there's reason for concern, right?

Cervidil is in place for 12 hours, though. The semen (at least for me, YMMV) pretty much removes itself, if you know what I mean. It's also not all jammed in the posterior fornix.

Prostaglandins are contraindicated because of chemical changes they make in the tissues of the cervix. Frankly, if semen had the same effect, I'm sure they'd warn all the VBACers off sex for six months before birth, "just to be safe".

From what I understand, since cervidil is synthetic, it can produce abnormal (much stronger etc) contractions.

I just found this in Ina May's Guide to Childbirth:

"Incidentally, the prostaglandins in semen have never been associated with hyperstimulation of the uterus, more-painful uterine contractions, fetal distress, or ruptured uterus."

So I guess that's that.
