Sex question

Hi all,

Throughout our dating relationship we never had sex.. and honestly we did maybe a half of time since we got married in 2017. I have a history w eating disorders and my hormones are so out of wack and I haven’t had a period in so long. This makes me not ever want to do anything sexual.

Honestly, his penis barely even went in me at all ever. I am always tense and it hurts. Not only am I worried that I’ll never get my period back, I worry that it will never actually go inside me to get pregnant if i ever get lucky to conceive. I am in my 30’s and I feel like a 12 year old.
