You are ignoring the fact that i said males like to hang around other males, and it makes it exponentially hard for a woman to enter the "club".

I assume you are a woman. Is your best friend a man or girl?

I'm a woman, and my best friend is a man. I have many more male friends than female ones in general, just due to my interests.

I've never once had the faintest idea of sex cross my mind when making relationships with co-workers or other male friends (I've been in a steady relationship for 7 years though, so it's not like I'm looking). Never once. And all my male friends I've made have never once conveyed anything sexual to me because they either don't feel that way, or if they ever did, they respect me enough to not make me feel uncomfortable (with the exception of one former coworker who I refer to as a harasser for his continual flirting + uncomfortable advances. I cut off all contact with him)

You're projecting tbh, many women are perfectly capable of creating strong platonic relationships with men. Usually it's the man who has an issue there, but that's not really my problem is it? If you think of sex any time a female befriends you and you let it get to you and damage your friendship, that's something you need to work on personally.

Also, do you think Gay dudes are unable to make friendships with straight guys for this reason too?

somewhat yes.

I really dont believe your best friend is a guy.

I'm a man and work in a sane work environment where genitals and drinking habits don't effect promotions -- especially among engineering staff where the whole point is to minimize the impact of those sorts of petty politics and instead focus on shipping product.

It's a shame we probably aren't in competing companies.
