[If with my girlfriend] I need to feel her touch and have the perception that she is enjoying..
[If alone] I need to concentrate on my touch and go back to my head.. Get absorbed in my thoughts and bring back my girlfriend or some fantasy.. Sometimes I also do it watching videos... I don't like porn but really enjoy home made videos with "normal" people enjoying themselves..

ps.: @ YOLO_Lady, Great Post!!

pps.: May y'all have a wonderful time this Christmas!
