I can understand how you're feeling, early 30's here and mid 20's I started getting curious. Couldn't place a reason but when you think of them, yeah, I tick a few boxes.... Is the way I thought. If the reason you're not indulging in a curiosity is because of your significant other then maybe don't if you think you'll feel guilty for it. If the. Thing stopping you from fooling around with a guy is "being nervous" or "scared" to try it get over it and take the plunge, I've been there for both and the latter is the one I'll tell someone to ignore their instincts/feelings on. Getting over the hump of fooling around with guys is for some guys difficult but I don't regret trying it out.
