It's my day off at work tomorrow so I've had a few several drinks and DP and I were mucking around and he called me a fat slag.
The slag thing, whilst not great, is a sort of an 'in joke' on account of me having a high libido to match DP but the 'fat' bit really stung.
I'm a size 16 (ish) and really not happy about it, I'm self conscious and insecure about my size and don't feel sexy at any time because of it so for DP to make a jibe about that really hurt 
Feel like I just don't want to have sex with him at all now. Maybe in 6-12 months when I'm skinny after having starved myself due to DP's 'joking'. Don't even really know what the point is in posting, I'm just upset.
