I found that black outs happened later on in my drinking years. I mainly drank alone in my house so my black outs essentially just were my waking up on the sofa wondering what TV program o conked out at
The thing I picked up on re your black outs is unprotected sex and if you're hoping to be in a relationship with the guy you like, then this could definitely jeopardize it. Not just the idea cheating but catching STIs. You could unknownly pass something to the guy you like :-/
I used to have friends like yours- even if I tried going sober on a night out, they'd start buying me drinks and my sobriety would be long gone. I ended up lying at one point, saying I'm on medication/antibiotics and that helped a bit
