One girl asked me when was the last time I had sex and then told me she liked it up the bum and she was good at blowjobs (not in that order I presume).
Hah! One of my best friends (female) used to use that line a lot (not on me, I hasten to add). I was pretty shocked when I overheard her, since she was remarkably picky about who she'd actually take to bed (again,not me, sigh), but she as she clarified: "if you have good legs you can wear a short skirt, if have good tits you can wear a tight top, but if you give good blow jobs you have to spell it out".
