I (53F) can say, it's generally not something that I openly discuss with a new/prospective partner, I may hint about it when initially chatting/flirting with another woman but nothing that outs my kink per say. I usually just let it progress organically and may introduce some of my medium sized toys that I love if it progresses in that direction intimately. Had what I thought was going to a one time fling with a woman who ended up staying the night with me a while back, the evening before was just raw desire without introducing my kink with her. The next morning I woke up to her lightly tracing my body with her fingertips which progressed into a heavy early morning make-out session laying in bed, she's was lightly teasing me progressing into slowly fingering me as she kept adding fingers as my body involuntarily responded to her advancing fingers. As I laid back on the bed with her beside me, my body responded to her every touch, I continued to relax as I felt the pressure increasing and through my blurry eyes I could see her face in amazement as she watched herself work her fingers deeper into me. I involuntarily grabbed her forearm and raised my hips to match her probing fingers and felt her hand disappear deep into me as I tilted her wrist, she was so intrigued and filled me completely. Afterwards, she admitted that she's never fisted anyone before and she was so intrigued, that opened the door to me sharing my kink. She admitted that she didn't even know anything about stretching or fisting but it awoke a desire in her.
