Being Into Sex

Annabelle
Ive been having sex with somebody new, its such better sex than who I was with before, but for some reason I cant get into it and get super wet like I could before. It feels really good and better than who I was with before and me and the guy have known eachother and are comfortable with eachother, so its kind of irritating that I cant get horny and wet and into sex with him, or like when once we fucked I came 4 times then the next time I couldnt at all and I told him to stop and I wasnt even annoyingly horny after having sex then not cumming like I normally would be sexually frustrated. Anyway would you guys have any suggestions? Were already going to try toys and restraints and things, since were already into that kind of thing, not because of this problem
