I've been noticing this a lot lately. My gf of over 3 years is a completely different person than she was when I first met her (sexually speaking). When I first met her, she was shy, timid, self-conscious, reserved, never talked about sex (even if she wanted it), and passive. After the first few times of us having sex, she's become outgoing (sex any and everywhere), comfortable (constantly stripping and teasing me), aggressive (often initiates sex and gives random blowjobs), and very verbal about wanting "my big black dick" as she so often puts it. She knew my size b4 we had sex, and was never verbal about it's size, but now she eyes me up and down like a piece of meat. I'm curious if any other guys here have had similar experiences. Also, if so, do you think it had something to do with your size?
