Yes, I think so. There are so many levels of friendship that don't involve sex. it could be a work friendship, a business friendship, Spiritual friendship etc. It is rare due to time spent causes a bond but if you have limits and know a strict purpose for the friendship then it is possible.

I got a female friend I haven't had sex with it I know way to much about her that's why I wouldn't, so yes it's possible.

I think so but they just have to have that understanding between both parties.
