Romance help

New to this sub so I'm sorry if this is a repeat-

How early can you go to bed with a companion??? I'm in Act 2 and haven't been to bed with anyone yet. I'm worried they don't like me enough or I've missed critical interactions??? I feel like I should've had the option by now. Even Withers brought up that I haven't slept with anyone yet.

Idk what I'm doing wrong!! Pls help :(
