Sharing an intimacy exercise I learned a while back from the best of my recollection.
This takes 20 minutes. Rules: No sex, clothes on. Touch your partner for 5 minutes how they want to be touched. Not sexually necessarily. Ask them things like "do you like when I cup your cheek? Do you like when I hug you tightly or do you prefer it softer?" Then switch, have them touch you how you want to be touched for 5 minutes. Then touch them for 5 minutes how you want to touch them with clothes still on. Switch for the remaining 5 minutes. Repeat a few times for a week or so until you learn everything or it's less awkward to advocate for yourself.
This takes 20 minutes. Rules: no sex, clothes off. Repeat the exercise above but clothes can be off. Still no sex. Repeat a few times for a week or so until you learn everything or it's less awkward to advocate for yourself. This is an important one if sex is painful for either partner.
Honestly I can't remember the next steps, but it was such an interesting exercise to learn how my partner wanted to be touched and teach them how I like to touch my partner. It gave a safe space to verbalize it and I felt closer to my partner afterwards. Taking sex off the table let us focus on the exercise.
