I am so sorry if anyone finds this offensive. Also I am sorry if I have posted this in the wrong place.
I am very confused on what to do about it or if I should do anything at all? It has been going through my head for the past few week.
My DP and I have been going through a rough patch over the past year, we have sorted things out. We have been together 6 years no DC.
We were having sex Tuesday evening... I admit I haven’t felt in the mood so much at the moment. I am on anti depressants which hasn’t made me feel too much like I fancied sex. It was standard him on top, me underneath. He had a bit to drink... not making excuses. I had also had a few glasses but that’s it.
We have been going through a few issues at the moment but I thought they were all sorted.
I felt myself getting dryer than usual. And it was starting to hurt me, usually with this type of thing I get cystitis (struggle with that a lot). I said ‘it’s hurting me now can you get off me’ and he didn’t exactly hold me down. He just got heavier on top of me and sort of did hold my arms... I can’t remember 
I couldn’t move put it that way. I also remember him saying something along the lines of... ‘take it’ as he kept going. It lasted about a minute or so after...
It’s still not massively clear in my head. We are just carrying on as normal, like nothing happened....
It did result in me getting cystitis and I had to get a round of antibiotics to clear it.
Would this be rape/ assault? I’m not really not sure as this has never happened to me before. Just because I am not massively upset by this.. does that mean it's nothing serious? I certainly didn't enjoy or appreciate him not getting off me but I didn't fight him off.
Thank you to everyone who had read this x
