Ok, then to be very clear, yes it matters a lot. I’m a slut. I’ve had an amount of casual and easy sex that it feels cringe talking about on the internet. I’m also married. I always start with flirtation and if someone doesn’t flirt back I stop. Because the alternative is to keep hitting on someone who may be uninterested, which is what creeps do. Theres a range of time that it’s ok to flirt without flirting back, but yeah if you dont initiate and you don’t reciprocate only creeps will ask you out
