Giving up on Sex (UTI)

I'm to the point where I don't want to have sex at all. My husband and I have been married for over 2 years... everyone around us is getting pregnant and starting a family.... we want kids so bad... but I'm scared to even have sex because EVERYTIME we do I get a uti! Never fails... EVER. I've been to the doctor and hospital more times than I can count. It's gotten to the point where we hardly have sex ever! We will be 24 next month... our sex drive is there.. I just don't want to have sex because UTIs are seriously horrible.
Before you tell me what to try.. I'll tell you what I've tried.
- Cranberry pills
- Apple cider vinegar shots
- Washing myself before and after sex (I stay clean)
- He washes himself and his hands.. but I won't let him go anywhere near my region with his hands even after he cleans them because I'm afraid of the germs
- Peeing before and after
- taking probiotic daily pills
- Cranberry juice..but a nurse told me pineapple juice is actually better than cranberry so I've tried that too
- Cystex
- drinking lots of water
I cry so much about this... I am to the point where I don't think I can have a child due to this... I'm at my wits end... and no matter how many times I try to explain how horrible a uti is.. for those who don't deal with it on a daily basis won't understand... I feel like a horrible wife too because I tell him no due to being afraid... this is ruining my life and putting a strain on my marriage (nothing like him leaving me or anything) but I cry and am upset all the time over this.. I'm depressed. It doesn't help that I see babies everywhere! One of our friends got married just a month after we did and they announced their pregnant with their second child yesterday.
