I'm well rounded whore. I do it all and love it all (except pain, gore etc.). It's all depends on person I'm with at the moment. Couldn't even count how many gallons I pumped in assholes and how many miles of dicks I've sucked. Meanwhile, keeping my completely innocent face and not pretending being a whore deliberately. Just enjoying good fuck with good people. Sucking each others dick or eating each others hole in 69 position is one of my all time favorite. From this point it can go one way or another lol
Although, I do prefer to bottom lately because I finally discovered how to relax and enjoy it properly. Even had anal orgasm hands-free. It blew my mind completly. And that comes from person who thought it's an urban myth. All thanks to a very talented top with just right dick.
Conclusion: try it all, do it all, stick to whatever keeps you coming back for more. We all have off-an-on switches in different places. Find yours and nibble on that sucker really good.
