Not really.

It's the description of a dynamic sexual act between two participants, using an orifice situated at the end of the digestive tract that has as primary function the excretion of solid waste from the body.

You'll be surprised to learn, that many people of all sexes partake in that activity fully willingly.

The context of the joke is as rape, your comment is utterly pointless and you know this.
