My girlfriend and I (both 22) have been together about a year and a half. She got the experience of hooking up and being wild. I (M) have never gotten that experience. Only a couple of makeouts. Occasionally, like every 90 days, I think about “hmm. It’d be cool if I were single and could hook up”. And then the thought leaves my mind. I love my girlfriend and am very happy. I do not want to lose the relationship. Her feelings are hurt that I think about being single. She says thinking it as a passing thought is normal but every 90 days is too often. Thoughts please?
I'm not sure why you brought up her own erst promiscuity, other than as a subtle sign of envy / grievance. She seems insecure or overbearing for seeking to control every fleeting desire (one could travel around the world in under 90 days).
But then I wouldn't want to spoil your happiness (and I mean that earnestly), so if you're more comfortable with a sense of guilt to avert your gaze automatically, as it were, you're welcome to try that.
