Hi GruffaloReader
I wanted to respond to your earlier question, as I think I know a bit of what you're going through.
I'm married (to a man) with 3 kids and have been attracted to women also since my teens. My DH has always known this about me, as I once snogged a female friend when we were just dating. The attraction to women has gone a bit quiet at times, but often rears its head - like you said. I have been through really difficult times when I've wanted to actively explore the gay side more, but have basically decided not to do so.
It is important to me that my (bi)sexuality is accepted and acknowledged within the relationship with my H. Sometimes its about having fun with it, and sharing fantasies, sometimes it's just casually mentioning who we fancy (sometimes the same women) in a movie or something. This openness is important to me.
Whether this is always going to be enough for me, I don't know. Sometimes I have a massive crush on someone and it does seem like an alarm bell going off.
You have to decide obviously what you need to do about exploring your sexuality, and no one here can tell you, but for me, internet dating wouldn't be the answer and the damage to your relationship is done once you start doing things in secret. You won't get any judging from me though. It's good to have somewhere safe to talk these things through.
