Personally,I have no problem teaming up with another girl of the hobbyists choice. [provided that she practices exceptional hygiene..that is a must!] True, some girls are comfortable with only certain other girls, which is good because then the whole experience is enjoyable for everyone (usully).
I do not need to fake it. As much as I love men, I find women to be beautiful and exciting. My only requirement is that they are clean and a nice person. The other girl being somewhat attractive and also being into the experience as well is also nice.   That sounds fun!   xoxo ~ Rachel T.
