got caught playing with myself by a woman in the sauna

so a a few days ago, I went to the gym and had a really good long nice gym session after I decided it would be a good idea to enter the sauna area. It was right midday and I was all by myself and I couldn’t stop and start playing with myself and enjoy the time I had alone, knowing that any time somebody could walk in.

exactly that happened the moment I thought I was going to explode the door opens and a beautiful middle-aged woman walks into me. I acted quickly and threw towel over me, but she definitely saw that I was hard and just had been enjoying myself. She sat across me and we chatted for some minutes. I decided to go out because I was ashamed as a window. She said she hoped that we’ll meet again soon and smiled.

i really hope i meet her again but idk how to approach her
