Haha yes definitely involuntary sorry to be a let down haha!
I don't actually want to reach orgasm through any means incase the uterine contractions cause bleeding also, however I may relax as time goes on as I haven't bled anymore after the sleep ones!
Totally understandable, that's how I felt and I'm still not really prepared to orgasm every day or more than once in a day. But I have orgasmed a few times since the fear wore off (I didn't till maybe 18 weeks?) and baby is still bouncing around. It's right for you to only do what you're comfortable with though, you don't want to send yourself into a panic afterwards.
