Too horny with bf

I started relationship with a guy for the first time, only dated women before this. My bf is pretty physical in general and I am way more horny with him. I probably did more in 1 month than what I used to do with women in 3-4 months. We keep making out, having sex at every opportunity. I am usually PDA shy, but have been doing an Insane level of PDA. I feel way more confident. Wtf is going on with me.
