This is a real posting, not fiction.

My current g/f was engaged prior to our meeting and while I have felt that she met me on a rebound she holds tight to denial. One of our issues is her penchant for anal sex imparted by her former fiancee who actually preferred her anus and did it a lot to her. She ultimately began to orgasm from the practice and preferred it for various reasons: his freedom to ejaculate inside her no matter how often. She told me how wonderful it felt for her and loved to squeeze the cum out and watch it with a close up hand mirror, ooze and drip out of her anus.

On my side the stench of human excrement gagged me and I could not tolerate it. The fear a major urethral infection, and I had one from unprotected anal sex with an airline stew. The doctor laid it all out for me, including a scholarly thesis on why shit happens, warning me to use condoms if I had to do what he called,
dealing with bacterial hell.

Wanting to please my g/f i explained my position and she agreed to prepare her poop chute with enemas and would accept condom fucks. She hated the condoms so I compromised and took the chance of quickly stripping off the condom just before I came, and plunging my quivering rod back into her asshole so she could feel the pulsating of my vibrating cock as it fired off deep into her rectum. We had all kinds of compromises but in the end, she found another guy who had yet to become infected from unprotected anal sex and was for it with her. Since it appeared that sex of that type was ultimately more important to her than anything else I was happy to see her flap off
with her hungry asshole agape.
