Well I'm a woman, and honestly, the first month and a half of my pregnancy I felt awful. I had morning sickness pretty much all day and all night, and sex was just about the last thing on my mind.

However, once my stomach was back to feeling normal, I wanted sex all the time. That part was all hormones though. I think what really made the sex better was the feeling of closeness we had. It's probably safe to say my boyfriend would agree to that. I definitely don't think he found me any less attractive

I never noticed my wife actually get horny in any trimester. I did love the way she looked and the lactating!

I'll answer as a man in this case: pregnancy, and parenthood, are a turn off to me. Especially pregnancy. Especially when you can see it moving around in there. I don't mean to be offensive, and I'm sure there are plenty of people who find it wonderful and a fascinating, but since the question was asking for opinions: pregnancy is not my kink.

The entire time I was pregnant I had increased sex drive. Even during the first trimester with the morning sickness. Once it went away for the day I was ready to go! My husband loved it just as much, though as things progressed it became a little uncomfortable for me. Not that I didn't want it, just hard to move

I don't want kids, and thusly I don't plan on ever getting pregnant, so perhaps I'm not the best person to answer, but whatever. The attraction to pregnant women always puzzled me a bit. Don't get me wrong - I can totally understand seeing one's wife or girlfriend (or even the female form) as beautiful no matter what.

It's just that my train of thought goes: pregnancy = babies, and babies =/= sexy.

My drive decreased dramatically each time. Usually I'd get a spurt around 25 weeks.....but for the most part total nose dive.

But....

My first I was violently ill until 24 weeks
My second I had bleeding issues
My third, I felt OK actually, but the other two were having sleeping issues.
My fourth (last! and current) I've pretty much been put on pelvic rest due to a massive ovarian cyst, until they decide what to do about it...

So I atleast had/have my reasons.

During both of my wife's pregnancies, sex was just phenomanal. I'm every bit as attracted to her as the day we married, more so actually, but I find her insanely hot while pregnant...just thinking about it (and pregnant sex) is arousing - which is a little awkward, because I'm sitting in my office at work right now

"Any women who have been pregnant, did it increase or decrease arousal?" HELL YES IT DID! Big sex drive increases with both pregnancy's (girl&boy). Actually, I believe I was pregnant when I found this site!! ha-ha.

I've never been with a pregnant woman, but has always been a fantasy of mine. I find the pregnant women to be extremely sexy

its not really a turn on for me, but when my wife was pregnant the sex was really good
