DOGGY STYLE AND ITS VARIANTS
This one's mainly dangerous because forceful penetration at the wrong angle can, according to Dr. Kristi Latham, a pelvic health specialist at Dallas's Beyond Therapy & Wellness clinic, cause vaginal tearing (which is least common in cowgirl thanks to the woman's greater power to control depth and motion). Additionally, according to Dr. Kat, deep and vigorous thrusts in a short vaginal canal can cause cervical bruising or even bleeding. But wait! There's more: issue associated with doggy.
"I'll often see from rear-entry positions guys going to penetrate the vagina and fairly often the penis will accidentally go into the anus," says Dr. Kat. "And because there wasn't any preparation, there can be anal tears and things like that."

Oral sex is a great fast pass to pink eye if your partner isn't as hygienic as he or she could be, leading to the introduction of fecal matter onto the cornea. But two parties engaging in the practice simultaneously is double trouble when it comes to the sewage-face conundrum.
TITTY FUCKING
You'd never expect this one, but apparently men run into trouble when penis meets breast.
"I've seen a few penile fractures, not just with the pelvic bone, but when guys are in the process of trying to give a pearl necklace," says Dr. Kat. "Sometimes they'll put so much force against the woman's sternum that it can fracture [the penis], and if you're not using any lube, the friction can cause some problems too."
MISSIONARY
Even the most seemingly boring, safe, and sacred position poses risks. According to Dr. Kat, while it's not as common as in rear-entry positions, it's pretty easy for women with short vaginal canals to suffer cervical bruising or other abrasions from deep thrusts.
