I'm in a nearly five-year long relationship with a man come June 5. I'm 35 now. I started transitioning three months before I met him in one of the worst areas of Philadelphia you can imagine. Here is a link to where we met!:
https://philly.curbed.com/2017/12/19/16792862/kensington-philadelphia-bridge-mural-photosAt that point in my transition, I barely passed; it had only been three months, and I had a very short pixie cut. I also dressed very andro. But, he said he saw me from afar and couldn't figure out if I was a boy or a girl, but that I looked really pleasant. In any event, we really hit off. And I'm really shy, especially around men. But he was funny and nice. So, we went back to his house and sat on his steps in West Philly til the wee hours of the morning. I ended up sleeping on his couch. At some point that night, I told him I was trans. (I'm actually intersex, but the difference means nothing to me, so I just say trans until I really know someone, as it is really confusing). He said he though so but didn't want to be rude.
I never thought I'd hear from him again but he texted several days later. Then, out of nowhere, I got a settlement check from TD Bank for overdrafts. You need money in a new friendship. I was poor. Dirt poor. Then, we started hanging out all the time. We moved in together by September and slept in the same bed. We weren't dating and he said he would never date me. Which, I accepted.
I don't know what happened but about nine months after we met, we had sex. Then, we didn't do it for awhile. Finally, we really started hooking up and I would say our relationship officially started around September 2014--15 months after we met.
My advice: tell the person upfront, especially if you don't "pass" well. If you do, only put it off for so long. Secrets kill relationships. And this secret may kill you. Maybe you could put it off longer, but I would always disclose before any "hooking up" beyond hand holding/hugging. If you kiss, tell him. Do you want to live with a secret forever. That seems exhausting.
BTW, my BF is from the Applachian Mountains in NE PA. He is fairly religious and conservative, though more apolitical. But, it works for us and he is totally in love with me. My life has been a nightmare. Did you look at the link? That's where I'm from. It's the heroin capital of America. Yet, five years after transitioning, every dream I ever had has come true: surgery, I'm super pretty, I have a loving amazing BF, and everything is going my way. If it can happen to me, it can happen to you.
However, if you really want a husband, you need to tell the truth. Unless, that is, you are willing to lie to someone about who you are day in, day out, hoping he never finds out. It's not 1980. What happens if he runs a search? remember, many guys, especially ones over 30, are much more open-minded these days. But guys are extremely insecure. All of them. Even if you don't pass to well, practice your voice until you get it right. This is prolly the most important thing of all. No straight man wants to hear his woman sounding like Barry Baritone. If you can get voice surgery and need it, do it. If not, go to a voice therapist.
I'm lucky, but I can sound like a man sometimes when I get mad. It's the only tell I have. Yet, if I don't get upset, I'm fine. Just practice. Always use your feminine voice. Not a falsetto. even if it is a bit deep, that isn't the end. If you can get it up to 160 hrz., you're gold. Mine registers at 180-220, but like I said I'm lucky. It also can go as low as 90, so yeah. I can't stress this enough.
