My (24m, straight) girlfriend (23f) has expressed that she thinks she's bisexual. She points out girls she finds attractive, has a few celebrity crushes on women, ect. I'm totally happy for her, I know she loves me and our relationship is rock solid (been together 3.5 years and are actively talking about marriage in the near future and have a very healthy sex life) But I don't want to be the reason she never gets to explore that side of her. Would it be weird if I gave her a "hall pass" to use with a woman?Obviously It's hard to know how I'd feel after it happened but I don't have any problems with it and am really not the jealous type. I just genuinely want her to be happy. I've joked about it a couple times and she seemed to perk up a little and seemed interested but has never pushed for it. I was thinking just a one time thing with lots of communication and clear boundaries. I'm straight, I don't have any sexual interest in men, and wouldn't expect or want a hall pass of any kind in return. The idea of a threesome has come up a couple times and she seemed interested but if the whole point is her exploring, I feel like I'd just be getting in the way lol. Idk I guess I'm just wondering if anyone else has experience with similar situations or any advice. Thanks!!
