Hmm... generalisation is always an issue. Women can't write sex from a male perspective. Men can't write it from a female, etc. It's like been said before: it's about research and how well someone can write. Bad writers from both genders write shitty sex scenes and the badness is usually not limited to the opposite sex.
I'm a woman, and I can't stand Anne Rice's flowery style. I like her plots and characters, but the overly descriptive writing is so tedious and makes it impossible for me to get through and enjoy it. So, I can see why a guy would make that statement about Anne Rice's male perspective.
However, it's a generalisation not only about women but also about men. Because this person can't imagine himself thinking in flowery descriptions, he is assuming no other guy on the planet can. I'll admit to finding that hard myself, too. I'm just as much a product of a gender-biased society as he is. But I've been around long enough to know that women and men come around in various flavours and we don't all experience things the same or in the way society thinks it's appropriate for us to feel. Just because I get a high from being touched somewhere, doesn't mean all women do. If only sex was that simple. XD
I find that I struggle with sex scenes when I write no matter whose perspective I choose. I don't want it to become like a manual to the reader. I want it to be engaging and exciting, but there are only have so many words and so many ways to write something that I sometimes want to pull my hair out whilst considering what other word to use this time besides, for instance, throbbing because I already used the word twice in previous paragraphs. I don't want to become repetitive in my sex scenes, but I find I do slip into a certain routine, too. And upon noticing this, I try to take a different approach with new stories.
However, I can't pull off the flowery kind because that makes me laugh and completely spoils the mood. I read a story by an author on this site once that had vague descriptions for parts of the human body and was still a really good sex scene, but for me that author was the exception to the rule.
And I usually start to snicker when I see things like "He stroked her holier than thou, untouched, sacred place". Okay, fine, not snicker but ROFL. However, I am sure there are others out there who enjoy reading that, which is exactly why generalising about these things is an issue no matter which way (from a male or female, writer or reader's perspective) you look at it.
Or at least, that's how I see it.
