beyder, do what you want. a bunch of guys on a website telling it's cool, doesn't make it right. one or two guys on a website telling you that you're trying to achieve something else by posting these pics should mean even less to you. if your girlfriend is cool with it, you're cool with, and most folks here are cool with it, then there's nothing wrong with it. only you know the real reason you're posting the pics. maybe you're bragging. maybe not. maybe you're insecure. maybe not. who cares? i don't. let your conscience be your guide and post at will. you have an attractive girlfriend. have fun. hell, i might even post a pic of my wife on here just for the hell of it. i don't care what anyone else thinks, i think she's very pretty.
bottom line, if you let rug bother you, your skin is too thin to hang around here. welcome, and have a good time.
