Put on a condom, first of all.

Then, make some jello. if you dont know how, look at the box and if it doesnt say go on google.

Then, when you made it, take a knife and cut a hole as big as you want.Prefferably small, or small enough so your dick can fit.

go on your hands and knees and insert your dick in the jello hole.
There's no pleasure to you, but it will feel like you are sticking your dick in a vagina!
