I'm never having sex again....

Here's just a little info on the situation-
I'd not had sex since I was 12 weeks pregnant my son is now 11 months. 
When I gave birth to my son, I had emergency forceps, and lots of stitches which has left me with scar tissue and loose skin around my vagina.
I've been to gynaecologist and she said they won't operate the now, and will only operate straight after I give birth to another baby. (Something about risk of infection)
Well I had sex last night, it was the most horrible sex I've ever had, my vagina feels so loose, like I could barely feel my partner's penis. I also couldn't lubricate myself which resulted in neither of us having an orgasm. I was so embarrassed that I started crying after sex.
I'm honestly never having sex again, I was so scared to have sex with my partner and now that I have, I wish I didn't because I'm miserable now. 
Why can't the gynaecologist just fix it the now instead of me having to wait till I have another baby, I'm so depressed😭😭😭
