Thankfully my wife is VERY anal. However, while we enjoy ALL aspects of sex together, there is no question her anus is FAR tighter and thus a more "strong" sensation to me then vaginal. Oral is...well just different. Incredible, but just so different then thrusting anal or vaginal it cannot be compared.

With appropriate lube, they should BOTH be very slippery. I find BOTH to be WARM. Thus, the real difference becomes tightness and overall "response". Her anal sphincter "grabs" and contracts between thrusts far more then her vagina could...naturally, so one is simply much "tighter" and more "responsive". Thankfully she too loves the feel of anal, so we BOTH enjoy it regularly.

OUCH...a fried onion ring would be rough from the coating. A baked onion ring would have no give or tightness. Nope...I will continue to enjoy my wives amazing little anal rosebud...as I have already (her idea) this morning. (I SO love that woman)...but I am going to stay away from having sex with onion rings.

Interesting. Glad you feel the same way...and thus have a happy agreement on it. To each his own. However, speaking physiologically....why , if it is that "off limits" was it put SO close to all the sex organs and why is it SO packed with nerve endings. As a woman who DOES have anal orgasms (more powerful, GUSHERS) then some vaginal ones, I cannot help but wonder about the concept "that is for waste only", when it CAN fill this duel function SO, SO, SO well.

Would have to be a SOLID onion ring. Those ones from certain Fast Food outlets...made from bits of onion. They would just FALL APART with the first thrust.
