I think it's totally OK to set boundaries with a nigga
Especially when ur just starting things off
If ur uncomfortable with something, make it clear and stand in ur mess
If he doesn't respect it, he probably doesn't have interest in building a meaningful relationship so show him the door.
But at the same time, being reasonable enough to where boundaries don't turn into strict limitations - in other words, not being a complete SQUARE. Fnfnnfn
Like, "OK I'm not comfortable with THAT but... BUT...I have an alternative in mind lolz" the alternative being something ur more comfortable with that may be just as fun or exciting for him .
U wanna stand in ur mess but u don't wanna come off as a buzzkill . Let's compromise a bit.
IMO
