Soft and sensual or more gymnastic?
How rough/gentle and why different at different times (that is normal, by the way, just give context so your partner can better understand you)? Define gentle and define the word “rough” to your partner. It might be better to describe your preferences, instead of labelling it.
Lots of room for misunderstanding here.
Who seems to have more knowledge about sex and how does that land with you?
Who leads versus follows and when does that shift, if it does?
If one person is predominately the initiator of sex, is that because you did not talk about it?
Is someone being, um, lazy or shy? Or at least is that the story in your head? How do you talk about it?
Give reasons and context, not justification or defense. The goal is to walk away from here knowing your partner much, much better in significant ways.
What questions did we not ask you to talk about, that would be really helpful for your relationship? Talk about those right now, please.
