Yes why not, I guess I am a bit confused still. I started off - almost too many years ago to remember - being a total dom. I think because that was my stereotype of how a male (drawn to bdsm) should be. So later a gf suggested she topped and out of curiosity I tried subbing. That was great although puzzling.
A marriage to a Domme did not work because we were both in far too much of a Dom mindset - she's now happy with a much more malleable guy. And I know I can't live permanently with an out and out Domme. Probably I'm about 60% sub nowadays and have two ladies I see - one domme and one switch.
We do not switch within a session or even a week - it's a longer timeframe and is a kind of reciprocal moodswing. And it's really difficult explaining this to anyone in advance so I don't blame everyone else if they are confused by the endless changeability of switches.
