According to Frenchie, our parents are ashamed of us, and no decent man or woman would ever want to be with us.
To any legit SO reading this, have enough faith in your gf's maturity and intelligence to trust that she can distinguish between fantasy and reality. Like Roast, I've had customers who have been regular visitors for years, and I have grown quite close to a few of them. Many of my customers (who would NOT be the type to concoct fantasy narratives on a stripping support site) are attractive and witty and pretty fun to par with, but that could never get in the way of my relationship between my partner and myself because, simply put, he's my best friend.
Daily, we share so many important moments together, sexual and non, that even trying to imagine a fun, hot guy on cam (again, fun hot guys don't troll sw) coming between us is a laughable proposition. To any non-troll reading this (perhaps even the OP, who knows), take whatever insecurity you feel and channel it into strengthening the bond between the two of you.
Talk, laugh, fuck when you're both feeling it, cuddle when you don't, (repeat) and support each other. Making her camming all about you and your concerns is the opposite of support, so don't dump a whole pile of your insecurities onto her. Through camming, she'll encounter her fill needy, immature men, don't add yourself into that category.
@Roast, I gotta laugh out loud at the whole 'camming gf fantasy' thing. Any legit SO would realize that we're not swept away by charmers who demand 'ass/tits/feet bb, then private' or buzz us demanding we 'open cam'. The powers of self delusion...
