Honestly the people that make me feel not lonely are not the ones I have sex with. Don’t put all your eggs in one basket; that’s how you end up in a codependent mess. Loneliness isn’t about romantic partners only, and friendships can be the most fulfilling things.
I mean not wearing a T-Rex costume to bed could be a dealbreaker for an intimate relationship. I’d find it more understandable than the number of former partners.
