You need to get past this one and the sooner the better. Agree with Tracey, it has never happened to me and no guy has ever made me feel unsafe or uncomfortable. In fact they usually go out their way to make you feel the opposite. I do a lot of men (scuse the pun!) Some have started off coming in to ask about other things, some come for another treatment first and then bring it up, they are nervous about being perceived as perverts. I have had a few say to me, I am so glad that I have found somebody to give me a good massage. I also did a lovely guy yesterday, stress oooooosing out of every pore and desperate for something to help. As it happens he won one of our vouchers at a Charity Ball, so it worked out well for him. It is very nice to see somebody leave you feeling so much better. Men get stressed just as much as women and they need a bit of tlc too.
Just go for it, you will soon feel better about it. It's a body not a date.
Be careful though about being on your own, that is something you do need to be aware of, though I have been on my own at times. Not worth putting yourself at risk, but really, can only say, most of them just need a good massage. The ******s usually know where to go and get what they want.
