Unexpected Attraction

I recently ended a long-term relationship and have been exploring my sexuality more openly. Last night, I discovered something new about myself, I was turned on by the idea of submitting to someone in a Dominant/submissive dynamic. It happened during an online roleplay with someone I've never met face-to-face. The control and power exchange excited me far more than I expected it would. Is this normal? Should I explore this further, or dismiss it as just a one-off curiosity? Your thoughts and experiences would be greatly appreciated.
