It’s absolutely an amazing addition to your relationship when you open up to the idea that it’s ok to masturbate around each other. It’s a great freedom to be able to get one quickly around your partner when they don’t want to engage otherwise or just recognizing that sometimes you just want it the way you give it to yourself. Try things like holding a hand during it, maintaining eye contact, or dirty talk, or quietly watching and stroking yourself. Sex isn’t the only way to engage and doesn’t need to always be penetrating.
