But so what? I was trying to get him to ride a metric with me at the end of May and he's kinda 'We'll see', that really bugs me. As if I had taken his toy away (but this is not a zero-sum game!!!). Does this have to do with testosterone or something
It probably does.

Some men can't stand to have a women be as good as them... or better.

It's that whole, "I'm a man", thang.

My boyfriend is sweet and wonderful in every way... except he is an EXTREMELY POOR LOSER. He will work out with me occasionally, but it takes a lot for him to keep a good attitude about him, when I am running faster and can go further.

Come to think of it... I am glad that he doesn't share any other physical activities with me. I appreciate his effort to share my activities... but it's not FUN when he is all grouchy because he's "not as good" as I am.
