He'll consider it??? The prostitute? Aw man i hope he doesnt go for it :(

its a more polite way of saying outright "No". Zig isnt saying it brcause hes considering to actually try, but more of saying it to politely say I don't need to etc. Or atleast thats how I understand how zig said it in context of his character

I've read the latest ln volume and i can't exactly confirm if he visits the brothel but I guess there are implications that he does, there was this one time when siasha smelled a woman's scent on him

he's not a celibate, he admits that sex is not of utmost importance but it's up there
