Like... with other people?
Um... yes? Are you fucking animals? (Dog girls don't count UwU)
First of all, all humans are animals (but not the reverse is not true). And second of all, I was making a joke about having sex with yourself. Does that count?
Only if you cloned yourself and had sex with him. Otherwise it's just masturbation and not sex. Sorry!
What about a version of you from an alternate reality, time stream, or dimension?
