Yes, just ask. They’ve heard it before Unless they say otherwise in their profile, they’re likely open to vaginal and anal, but you shouldn’t switch from anal to vaginal without a good cleaning. Also, water based lube only at the vagina IF any lube is needed. Also, you don’t have to be as gentle with a vagina on entry like as ass. Also, the testosterone makes their clit huge…don’t expect that from a cis woman if you ever go there
Finally, it’s highly likely that they are sterile either chemically or surgically. But again, you should respectfully confirm they’re ok with you cumming inside
