Had somewhat of amazing sex again

Well I had a MC 3.5 weeks ago now hub wouldn’t play just casual normal sex and that was it. Finally a couple nights ago I got some omg! I could have went all night. He hasn’t been that way in so long I didn’t want him to stop. I think he’s been watching videos to get ideas. I’m a complete bdsm girl and well total sub. I pretty much do anything. And my thing is pain, lots and lots of pain.. holy shit I can’t believe all the things he did.. wowza. One thing I hate is he does this and then it’s like boom your cut off for 2 weeks. Wtf! Tease me with it once and no more I can’t handle that.. I need it so much. We used to have sex 2/3 times a day now I lm lucky if I get it once a month and we both have crazy sex drives so idk what is going on. All I can think is he isn’t attracted to me anymore or he’s cheating because i have to almost beg for it. If he wants it I give it no matter what because I’m dying for it. When I do most time I get nothing. Any ideas how to spice it up and get us back on track please! I need help! I want my sex life back I can’t be sexless.
