You know you’re fucking her good when after the ordeal: she doesn’t want to stop cuddling with you, wants to continue doing it, texts you often, wants to see you often, stays as long as she can at your place or doesn’t want you to leave her place, and lastly: hinting about relationships
Some people also have low set cervixes, meaning that just slamming in there can actually really hurt. Foreplay, communication, and easing into it is really important. And if you like rough sex, there are other ways to be rough than just slamming yourself in there with a stagnant and boring rhythm. Roughness ≠ fast and aggressive thrusts.
i will say, at least in my experience, when i have told men (gently either during or after) i’ve gotten tears and blame, name calling/screaming, and have gotten hit. some men can’t handle constructive criticism and so we don’t feel safe saying it. not all women/all the time but that’s my experience and im sure some ppl feel the same way
