There are a lot of guys who focus on exclusively topping, to the point where I think the ones who don't are exceptions rather than the norm! Roth and Gunnar, for example, have exclusively topping scenes, while the only one who only takes rather than gives that I can think of is Logan (And even he is very much taking control of the situation!).
A few others do depend on your actions, though - from quickly poking around, I noted that the Harold is dominant if you have higher bitch fame and submissive if you have higher hero fame, for example. And a lot of the opponents (such as I believe all the bandits?) are more than eager to plow you. So if you're looking for more 'opponents take control', it may help to raise your bitch fame to encourage scenes like that. For example, uh, I have no idea how Bernard reacts if you are more submissive - he seems to be used to being in control and is surprised when I stepped in to do similarly. I wouldn't call him /submissive/, though, minus love potion shenanigans.
While I personally went dominant myself in my main playthrough, I did notice from poking around that a lot of scenes change a /lot/ if you go submissive, particularly losing choices with the meeting with the merchant/bandits on the track, haha.
Keep poking your head into the Track to begin Arion's quest line - doing some quests in Bareshade seems to lead you to him swiftly. Once there he'll show up in Bareshade itself, then after some more time will hang out in the stables (both within the tavern).
