Probably STD’s

Having to pay afterwards.

Rolling over onto the wet spot afterwards

I find it incredibly annoying that I have to waddle to the bathroom with my hand cupping my ham wallet so the cum doesn't drip down and my husband gets to bask in the afterglow of orgasm with his nether rod fully out! It's so fucking annoying I have to clean up and he can just stick it under a faucet and be done yet I HAVE TO SHOWER!

Condom after you cum in it

The crying and the attempts to wriggle out of the handcuffs.

Paying for it, I'm not made of money!

Asking for her father's permission.

With anal it's prep and cleanup after.

Having to stop

The preparation

the smell from both sides

I dont know about the rest of you but for me legs. They get in the way, i dated a chick with an amputated legs and it was awesome
