Depends on the girl. I'd like it if it was a boyfriend doing it, but not a regualr guy friend. You could always start off by asking the girl you'd want to give the massage to. Or you could put her legs across your lap and work your way from there. Start massaging her legs then take off her shoes, socks. If she starts to pull away, then you should know that she doesnt want a massage. Hope I helped. Good Luck.
