By way of a warning, if the following offends you then either stop reading this or stop writing utter drivel.
(Start of rant)
Story descriptions with spelling mistakes, missing words, bad grammar. If the description contains such errors, it is likely the story does too. So use a spell checker, read it before you post it. Hell, read it after you post it then go edit it..!!
Awful descriptions of sexual positions, non sexual positions too. I realise that often authors write about what they would like to have experienced but never have, but at least picture the action you are describing. Hell, go out and buy two dolls and pose them, just stop describing the impossible. Example. If she is on her hands and knees, he is fucking her from behind, he cannot lick her clit whilst still fucking her, it just is not possible. So stop describing the impossible.
What exactly is so confusing about the word 'lesbian'..?? Any author ought to posses or have access to a dictionary. Use it..!! I'm sick and tired of stories that include the male MC fucking the lesbian(s). If he is fucking them, they are bisexual, not lesbian, moron..!!
If the virgin in your story is going to lose her virginity, go look up exactly where the hymen is. Please..!! If you don't, and you get it wrong, than apart from annoying every female reader, you are displaying your ignorance for all to read. Would you read a car report written by someone who had never been in one, let alone driven it..??
If you are going to include a kink or any of the more exotic sexual acts, at least do a little research. Guessing only displays your ignorance. In your fantasy anything is possible, but when writing a story intended for others to read, the likelihood is that at least some of your readers will have practical experience of the acts you describe. If your story includes acts, attitudes etc that are inaccurate not only do you risk losing those readers, it makes you look an idiot. So either write from experience, or do a little research..!!
Facials are wish fulfilment for a lot of guys, girls too, actually. But if your cum gets in her eye you will not be popular. It stings. A lot..!! Don't believe me? Go jerk off and rub some in your own eye. You will not do it twice..!!
Before you write about anal sex, either try it, or stick a finger up your own ass. (Pause) Now try it with lube. (Pause) Now deeper. (Pause) Think maybe an enema would improve things? (Pause) Get my point..??
