Clarificiation, inclanation is shown in their profile, right? Next to their personality and stuff?
Yes, but you won't know right off the bat what a stranger's sexual inclinations are (unless you have cheats turned on), you have to get to know them. If you're looking specifically for a dominant or submissive person and don't wanna cheat or date around a bunch you can use the Findr app on your phone to find people with those inclinations right away.
