Please give me some advice

Hi. I broke up with my boyfriend who I loved so much and had a long serious relationship about 3 months ago. Now I just wanna have fun and hangout with some boys. There’s this guy that I met on instagram and he’s really hot but it’s obvious that he just wants sex but to be honest, I’m ok with that. When I tell my friends that I’m gonna go to his house and maybe have sex they act judgy and they’re like “omg! Are you serious?” I want to talk to some non judgemental people and get some advice. Is what I’m doing okay?
