I've not reached orgasm is about 5 years. Help!

Emma • 24, mum to a 3 year old boy, DV survivor.

I know it's a strange subject...

I'm 24, a mum of a 3 year old and in a new relationship, im really struggling to reach organism alone, using toys and also during sex. I recently almost got there but my body must shut itself down, I feel really crappy about it. I know it's not that important but i feel as though he's moaning that I'm not having an orgasm during sex and feeling as though he's a failure!

Any top tips? Did any mums struggle post pregnancy?
