Sluttiest thing you've done after leaving Islam?

Guy here. So after leaving the faith, took me about a year or so, but finally started exploring the world of sex in undergrad. Best thing that happened was a threesome [MFF] (involving ex-Muslim from childhood, and one of her friends). Wondering if people had similar experiences? Have to admit though, sometimes I feel dirty/guilty, which I suppose is my old self lingering in my subconscious. Difficult to explain, but has anyone had similar experiences?

Girls and guys welcome.
