Sex with another man... ?

So It’s been 3 weeks since I got out of my 3 year relationship... and Im sooooo horny . ( I know tmi ) anyways I really want to get some ( if you know what I mean ) but at the same time I’m scared bc I’ve only ever had sex with my ex .. and also idk if having sex with a complete stranger and then cutting ties is for me

Should I just go for it ?
