How do I tell him I actually liked it ?*long post *

Well a few nights ago I was in a absolute horrible mood period is not even two weeks away so I know it’s pms and hormones , unfortunately my lovely fiancé has to deal with this every month , usually he’s pretty chill about my hormonal attacks and doesn’t pay me any attention but I guess this night was very different . He came home from work and was in a relatively good mood . Until he saw that the dishes weren’t touched (because it was his turn to do the dishes anyway ) and the kitchen wasn’t clean (again his turn ) he asked me to do it calmly and of course I said a very bitchy no . Which I guess made him angry but not to the level of what I expected which was to come later . After that ordeal he kept quiet and so did I until it was time to lay down . When he was shaving in the bathroom he asked me to hand him a towel . I said no again silence fell but the kind of silence you don’t want .. pissed silence

He then walked back in the room and said “I told you to get the towel *my rl name * “ I ignored him because I was already in a pretty bad mood for no reason lol that’s when he grabbed me and flipped me over and held me down by my back and started to smack my butt , the hits were extremely hard and loud and he kept repeating I’m sick of your attitude and your smart mouth he was completely chastising me but I loved every minute of it this was the first time he’s done anything like this and it shocked me at first But ever since it’s happened I’ve been replaying it in my mind over and over . However he feels horrible about it and I don’t know how to tell him I actually like it without him thinking I’m just saving some face ..
