It sounds like THIS relationship isn't for you.

Better yet, demand she hands over her phone, unlocked, and scroll through her messages. 🤷 Idk. If she has nothing to hide she won't balk at it.

Or maybe those, "mutual orgasms," aren't so mutual and she has to get herself off? 🤷 They need to have an uncomfortable but necessary conversation.

Why are you embarrassing her over masturbation? She's a human. It's done by like, nearly every adult. She's clearly lying because she's ashamed/embarrassed. Y'all need to have a discussion about it. Tell her you don't give a flying fuck if she masturbates- it's normal, and she doesn't have to feel like she should hide it.
