Can anal sex cause an orgasm?

This is primarily due to the fact that during anal penetration, the penis pushes against the G-spot and stimulate it

In some cases, this pleasurable sensation can be strong enough to bring a woman to orgasm 

Men are also able to reach orgasm during anal sex, but the event is quite rare for receiving partners. 

During anal penetration of a man, the penis pushes against the receiving partner’s urethra.

The stimulation of the urethra can induce strong sensations, but these sensations are generally insufficient to lead the man to orgasm.
