I think I can kinda understand how you feel curiouspan. I am also in my 40's and just coming into terms with myself. I currently identify as bi-gender. Some days I feel feminine, some days I feel masculine and have dysphoria about not having a penis and then other days I just don't feel like anything, I just am. My husband is ok with it as long as I am not in male mode around him (he's a truck driver and gone a lot). I didn't really realize how much I needed to be able to talk about it until my niece moved in with us and told me she was bi-sexual. I couldn't help it. The words I'm bi-gender slipped out of my mouth before I could think. I was terrified that she was going to think badly of me. Thankfully she was totally cool with it and we can talk. I hope I don't push her too much. I've never had someone (in person, on the computer is different) to talk to about it. She was also worried about telling me and was relieved when I told her.
As for wanting a penis, I can relate. When I was a kid I used empty to rolls as a stand to pee (stp) device. I quit eventually but every now and then I would try to figure out ways to pee standing. One day I saw a meme on Facebook about the she wee. (That was 3 years ago.) I started researching the internet and found a whole bunch of stp's both made for women and trans men. I started with the she wee thinking that just standing to pee would be enough. At first it was, but then I wanted one I could wear on male days. My husband was ok with the she wee as I'm an active outdoors person and squatting in the woods sucks. He wasn't as ok with one I could wear so I got a fenis original. It's not phallic shaped and not flesh tones. He was only ok with it when he's not home. Unfortunately the fenis didn't work so well for me. Then I got the Sam STP from New York Toy Collective. It was ok shaped, a solid flesh tone and amazing, but still not enough. It was too stiff to pack/wear the way cis male does. I had to flip it over to keep from looking like I had an erection. Not very masculine feeling to have to flip over and reposition your penis every time you have to pee. I want one I can just ship out and go. I'm currently saving up to buy the che 2&1 from T-Men's Junk Shop. It is very realistic looking but I'm not sure about the recptical. We'll see.
I hope something in my rambling story is helpful to you.
