I divorced twice because of it, without even transitioning! Switched to men for a while, but really prefer women, at least for relationships. A roommate (female), with whom I had a totally non-sexual relationship, but knew my situation, connected me to a friend of hers she knew to be accepting. We have been married 25 years. She has a bit of butch, and quite frankly enjoys my housekeeping/cooking skills. Only occasionally does she get ticked when I explain how to correctly use some appliance. She loves watching sports. Thank God she doesn't drink beer, kicked back in a Barcalounger, farting, while doing so. I am into the Arts. Our relationship works because we do not try to takeover each others' "specialties." We actually have all the same skills and interests as any "straight" couple, except that it is distributed differently.
I think that SOs are out there, you just have to advertise what you want, and what you have to offer. No Surprises. You may find it easier at 30 than at 20, because at 20, women haven't yet figured out that Prince Charming has ridden right past her house. At least that was about the time I figured it out. Comfortable may not be a castle, but it's safe, clean, and happy. Hopefully, that's enough.
