The problems with male homosexuality are not restricted to anal sex...

What problems?

...though I am sure this practice is harmful to all who take part in it whether hetero or homo, willingly or unwillingly.

"To all"? You're "sure"? How are you sure? Harmful how? How many people have you discussed this with? Is there an underlying suggestion here that a lot of people partake in it "unwillingly", more, say, than who participate in other kinds of sexual activity? Hadn't you better apprise us of how you gained these insights?

I am sure few women willingly take part in anal sex.

And how many women have you asked? Quite a large number, one assumes, as you're so "sure"? Did any of them slap you, by any chance?

I am not "fascinated" by it, I find it completely disgusting and am sure it can have little to do with emotional attachment.

Not "fascinated" by it? Yet you set yourself up as a fount of knowledge about how many people partake unwillingly or who are "harmed"? That it has nothing to do with "emotional attachment"? Au contraire, you squirming little liar, you are totally obsessed with it in the most disgustingly unhealthy way imaginable. Sick in the head, I'd say, to put it rather too kindly.
