How old were you when you began questioning/considering you weren’t “normal”? I’m in my 30s and almost all at once feel like I’m not sure what I am in most demensions and struggling to figure out what I feel about anything. I’ve been married, happily for a while, which adds a little to the confusion.
I was in high school when I started to realize that I was bisexual. I started questioning around Grade 11 and 12, and then came to terms with it in my first year of university. However, it didn’t really change anything for me. I was in a long term relationship at the time, and after that one ended I very quickly ended up in another relationship which I’ve been in ever since. Both of them were “hetero” relationships.
Knowing that I’m bisexual hasn’t changed my feelings for my partner. All it has done for me is help me accept that what I’m feeling is normal, and that it’s perfectly okay to be attracted to both males and females.
The fact that you’re happily married shows you still love your spouse. Questioning your sexuality doesn’t have to change anything about your marriage. If anything, I would talk to your spouse about it and go “hey, I’ve been thinking about this a bit, and I’d like your support while I try and work through these feelings.” You can question and work through it without having to “experiment” or look for anything outside your current relationship.
And remember, being in a “hetero” relationship does not invalidate your sexuality. You don’t even have to label your sexuality if you don’t want to.
