I really don't ever see myself transitioning, though I do like the phrase Transitional Exploration.
When I was in my teens to early 40's, I was so hard-core bisexual, I had serious considerations of becoming full-time gay, though I never did. There were many many years that I exclusively sought out & maintained male sexual relationships. In those times, I still yearned for sex with women. I just enjoyed both sexes too much. In fact, it's been over 10 years since I've enjoyed sex with another man.
Don't get me wrong, those were some damn fun times, but I'm happily married to a wonderful woman. Although she is unaware of my NBE, she does enjoy my shaved legs & she supports my skirt wearing around the house. Um, I mean, my homemade kilt wearing. LoL. In fact, she made them for me. While she has several close friends that are lesbians, when my tits are more noticeable, I don't think that will be a problem. If it is, which I doubt, I will cease PM, for she is definitely a soulmate. I will probably double-up on NBE Foods at that point, though. LoL
Sorry for straying from the OP ... I do like the phrase Transitional Exploration.
I'm 1,000% sure I'm not going to transition, and I fully support those that do, "it's just not me".
