How many people out there can be ''just friends'' with the opposite sex?

Absolutely. I have plenty of guy friends. No problem, and no physical involvement beyond the same greeting hug I get from my female friends.

One of them I'd learned along the way had carried a bit of a flame for me for years, but was respectful and smart enough to never have actually tried anything. Friend crushes are pretty common anyway. We're very good friends, and he remains one of my husband's best friends. You need to be mature enough to deal with your feelings if they're not appropriate.

I can.
for some reason I get along with guys and with my girl friends [[[=

They can give great advice

My best friend is a guy and I used to like him but know after getting to know him, I love him only as a friend. I talk about more things with him then I do with my "girlfriends".
its great to have a guy to talk too.

I can! I have soo many guy friends;;
and its great!
you learn so much about them just by watching them.

3 of my closet friends are guys and they're better friends to me than any girl has ever been and yes there straight lol

Some of my guys friends I am just friends with, at least most of them. But my best friend on the other hand madly I'm love with him only make out but would marry him when I'm done with college. Depends on the physical attraction I guess and the chemistry there.

Yes, as long as neither of you wants anything else. It only gets complicated if one of you has stronger feelings for the other and those feelings aren't reciprocated.

I can if I'm not attracted to them.
