I once went to Krabi with my exgf and we went for a couple massage. It was very romantic and over looking some forest. we were only separated by a thin partition - those bamboo type. I remember we went for a 90 min massage.
It was so good I snoozed for maybe 15 mins. Woke up with a hard-on and the maaseur asked if I wanted a cock massage. BUT I DIDNT DARE COZ MY EXGF WAS THERE.
Regretted since and no chance also since then... sigh...
