Along similar lines, I wanted to go with a girl who was really tall, six foot when she's bare foot. I requested she wear killer heels as well. When she answered the door she towered over me, she must been at least six four maybe five in her heels. I'm five eight by the way. She looked magnicent and I had proper good fuck session with her.
In the real world that just wouldn't of happened, not for me anyway.
Did she think I was some short arse dick? Who knows! But I well enjoyed myself.
What I'm trying to say is, it's no point worrying what they or others might think. So what if she's thirty, forty years younger, who cares and if she does, she's in the wrong job.
