I wanna be in a t4t relationship where my gf gives me kissies even when I don't want her to :3

Hi, inexperienced hypersexual tgirl here. Let's say hypotethically you're with your partner and they keep kissing you and touching you sexually while you say stuff like "No, not now" "Can we do it later" "Not right now" is that bad? like is it a bad thing that makes one feel bad?
