Ok, I'll input into my experience on this. I never thought much about this, but . . .. . . one lady suggested it once, so I thought - "Well, why not, let's try it". (from her to me).
So - without going into details, we tried it (her on me). My thoughts were...It was certainly a Personal experience, but I'm NOT sure it was a Turn-On/Sexy thing, if that makes sense??
So - I'm not sure I would chase this activity, as mentioned it was different, but not sure it was a turn on. Definitely a personal, unique situation.
