Transgender is not a verb, it's a noun
As such, "transgendered" is an incorrect usage of the word. You don't get "gayd" or "lesbianed", right?
Also, not all transgender people want vaginas...
Vaginas certainly have a lot of maintenance. You need to wipe a certain way, make sure it's clean but not too clean or you may leave yourself open to yeast infections, UTI infections and stuff like that. Not to mention cleaning it after sex is a tad bit harder than a penis...
yah vagina maintenance is crazy compared to how easy it is to keep a dick clean
