@[email protected] I think the real question is what happened when he climaxed?? did whatever fluid he left behind eventually just transform back into his natural goo state or....??? 
@[email protected] I’ve put some more thought into this and I think I’m convinced now he doesn’t actually have or make genitals I think he just turns part of his body into goo and either penetrates or gets penetrated by his partner as needed and presumably there’s no fluid release at climax for him and maybe it’s not even about that but just the sensation of being close to another entity?? he always helps his partner climax tho
