Good for you! I'm happy you enjoyed it, broadened your experiences, and tried something new.
And I agree with pretty much everything you said based off my own experiences with women/transmen. Vaginas are softer, ribbed, have more even grip. Anal has more friction, is tighter, and gets tighter the deeper you. Also easier to go balls deep with anal whereas the average vagina is 5-7 inches deep and your partner will pull away if you go deeper as pushing up against their cervix is painful. I also feel like anal is warmer than the inside of a vagina. Overall I personally have a preference for anal over vaginal but both feel great of course.
I'd recommend anyone to try both and experience new things.
