I'm still fairly new to all this but I do usually like to communicate after a visit, usually with an email just to say thank you (and I like it when I get responses back as well.) I like to enjoy myself but want my companion to enjoy herself as well, which makes the whole experience better for me. (It's a vicious cycle of awesomeness lol)
A thank you sent and received is the icing on the cake........I'm sure I'm not unique in wanting not only a physical connection but somewhat of a personal connection as well. (like good friends) A note afterwards make it seem even better or prolongs the experience.
Thanks to all the ladies that took a chance on seeing a new hobbiest, I especially enjoyed a visit over coffee with an awesome lady prior to the visit visit.
