Goldstein says “overaggressive anal douching” (i.e., douching with too much water or force) and the angle of the top and bottom’s pelvises are additional factors to consider. You can even play with a lubricated toy to both lube and dilate your hole before the action begins. Lube can be applied with a finger (which makes for great foreplay) or, if your toy or partner is large, a lube injector. I favor a thick, water-based lubricant or silicone lube for anal sex, and applying it to the penis or toy, the b-hole, and inside the hole, since penetration often reaches deeper than the rim area.
The bum doesn’t self-lubricate like the vagina, and, since spit doesn’t contain the proper lubricity to ease penetration, one must invest in a quality lube (and lots of it) for a more pleasurable sexual experience and to prevent injury.
What that means is if someone goes beyond their capacity (i.e., their hole is opened up too wide or with too much force), any of these components can tear or develop other complications.” “The anal cavity encompasses skin, muscles, and blood vessels, each of which can be restrictive and limiting. “Anal sex is a high-pressured act with significant forces at play, all of which can be quite traumatic,” Evan Goldstein, D.O., CEO of Bespoke Surgical, a medical and wellness practice for queer men, tells TheBody.
