how likely is it for me to go into labor if I was to have sex and my husband nut inside of me

I don't think it's too likely. However I have heard sex helps the process.

semen softens the cervix too in large amounts so it might help if you keep going at it over and over lol

Not likely since you are only 33wks. It does help soften your cervix but it isn't gonna do much right now.

Okay I ask because I am scared to have sex with him so close to the end of my pregnancy and I hate telling him no

Yeah I really don't think there is any harm in it, unless your doctor specifically advises you not to do that. Isn't gonna do much until you're basically ready for labor anyways!

well I have two dislocated hips

Lol then why are you wanting to have sex anyways. That sounds awful.
