The Vagina. It's not icky, it's not gross, and it's certainly not the magical carrier of all terrible diseases. You can cut that shit out now. If you're following me, you're hopefully an adult, and that's how I'll be treating you for the rest of this rant.

To start with, what most laymen consider the vagina is -actually- the vulva. The vulva includes not just the vagina ("the hole") but also the Labia Majora or "outer lips", the Labia Minora or "inner lips", the urethra, and the clit.... if you can find it.

The Vagina itself is the inner canal between the entrance and the cervix. It's usually 4-7 inches deep, and protected from pathogens by the labia as well as the lubricant's acidity.

You do not penetrate the cervix during sex. You do not want to slam into the cervix during sex. You do not try and force semen through the cervix to fertilize the egg. The cervix is a solid barrier and the mucus protecting it will not let fluids through like that.

The vagina does not get "loose" from sexual activity. It's a muscle group like any other, the more you exercise your muscles, the stronger and more enduring they'll be. Child birth can cause connective tissue to tear, making muscles unable to properly contract.

The shape of the vulva does not change with sexual encounters. It's mostly genetic, with a few outlying factors. You can't tell how much sex someone has had by looking at their vulva.

Despite what Anime has said, consistent vaginal sex with a single partner does not "Grow the penis"

Vaginal lubricant is not a stronger transmission vector than either semen or blood. Always practice safe sex, and use condoms.

The most common STI is HPV, it's nearly invisible unless active, it can be communicated even in it's semi-dormant state, just at a significantly lower risk. USE COMMON SENSE AND CONDOMS.

The human mouth has the highest bacterial level, followed by the colon. Sorry to say it... your asshole is not cleaner than the vagina. And your mouth is absolutely filthy in comparison.

People shouldn't be worried about the vagina being "icky" for oral, the vaginally endowed should be worried a filthy mouth getting near their bits if cleanliness is the worry.

Adding lube if things aren't working immediately isn't indicative of anything but lube being needed. Seriously. Lube is great, and should neither be a point of shame, or seen as dirty. It's a tool to increase pleasure.

So, in summary, as with all sex, be safe, be courteous, stay clean, get consent, use a condom if you're at all unsure, and have fun.

Also, even if vaginal sexual contact isn't your thing, it's not gross, just not your thing.
