I don't know how often you get asked this question, but I will ask anyway.
Have you ever had any clients whom you've cuddle with ask during their session, "May I listen to your heart?" or "Would you like to listen to my heart?" If so, how often and what specific time of the session?
I ask this because as a sex-averse, touch-favorable asexual male, I believe that listening to one's heartbeat is not only the ultimate in achieving intimacy, but also a perfect alternative to any sexual activity I'll ever engage in my life. Just so you know, I always ask before I engage cuddle-wise.
