In Joshua’s previous real life experience, he had attempted to suck dick and play with a guy only a couple times. I think he is exploring his bi-side with us. Previously it was more of a “I’m really drunk, let’s try this” kind of thing.
He was down for sucking Ransom in return. ‘Excited’ might be too strong of word, so I think ‘eager’ would be more appropriate to describe his enthusiasm.
