Don't be worried about your rooster size as long as its not ridiculously small, an average richard used correctly can still be very peasuring.
just saying that most (teenage,13-19) chicks like 5-8 inches. if you are under that you should be prepared to compensate or be able to deal with some lame love. ive had multiple female friends tell me that banging dudes with smaller richards is just 1 way mostly, since most guys aren't love pro's.
i have to agree with most of what dottyboy said although js, going down on her after you've banged her for a bit does not sound like something i would want to do, i mean my richard was just there so...
