Yea, I had the same reaction when I first started. What you mean I'm not the only weirdo, there are other guys that pay to massage the girl?
Some girls found it odd that I include a chest exam while my tongue technique may be too wet for most (kidding)...
Ask the girl what's her comfort factor, otherwise if chemistry is not right, she may just tense up with lots of forbidden zones. Take your time and don't dive straight for the goods as that's my problem I'm usually too tired to give my technique any justice. Sorry, I don't do guys.
If your massage skill is good to great, you may be rewarded. While others just love to give out reward for good effort. Some just love to be touched and let our fingers do the walking. And then there are those that use it to get a break when they are really busy. Enjoy, have fun.
