I think gender does come into play a little -

My BF and I used to go riding together all the time, him on a schwinn hybrid and me on a schwinn leisure bike. He had skinnier and larger circumferance tires plus was stronger. I was always pushing to keep up and usually was half a block behind. (we did have a talk about passive aggressive behaviour patterns

I was sick of always being behind so for that and other reasons I bought a Specialized road bike. NOW I could keep up no problemo.

On one windy miserable day I was drafting off him and he turned and said "Haven't we ditched you yet?" OOOOOHHHH not a good thing to say

He is overall very cooperative, polite, fun, and just an all round nice guy UNTIL a girl passes him
