Single after 7 years, new me, new sex, love or lust?!

I’ve been single for only two months after being in a 7 year long relationship (I know, holy shit) I met someone immediately after the break up. He is the sexiest man I’ve ever seen in my life and I’ve never been more attracted to someone. My sex drive is literally through the roof, my sex style has changed, I’m incredibly submissive and will do anything with the man. And I think about him and having sex with him constantly. I will smell his cologne on my pillow and my breathing literally stops for a second. He is very obsessed with me, I’ve fulfilled everything sexually that he has ever wanted (he is incredibly rough and dominant). The emotional portion of our relationship has been intense from the very beginning to the point where we have to RESIST from saying I love you. What the fuck is going on here?! I am not naive, but I am very caught up and confused where this all came from. Is it love, or just lust? Things have settled down already (as in the initial intense sexual tension has settled, I used to literally get so wet I would have to change my underwear whenever I was just standing next to him). Our sex life is the most open, trusting and healthy sex of my life. Please give me some insight ladies. Real women lift others up! Peace and love.
