How would you tell someone that you love that you aren't into sex anymore?

Question

I have 6 weeks left in my prenancy and all he wants is sex or sexual contact, and i don't.

Answer 1

"Honey, I am just not interested in sex right now, it happens during late pregnancy".
If he needs some release, perhaps you can hold him and help him with a hand job, or whatever. But, he needs to understand this is all part of making a family, and deal with it, hopefully responsibly.
