Dane and josh were just the same. Josh was just straight so he only do with women (he had done with 3 women at once) and dane do both. Dane and josh ahs done with different ppl in the same room as well.
Josh only stopped after having pete and Dane will also stop after falling for Grayson. Same with Grayson, he will stop once he did with Dane.
From novels:
Think about how you were, Joshua Bailey. I didn't know you'd become this well-behaved either."
"People call that settling down, Dane. And I still had more restraint than you."
That wasn't the end. Joshua shamelessly added one more line.
Joshua patted his shoulder as if comforting him and smiled brightly. Seeing the fresh smile, Dane was incredulous.
"Who was it that went around clubs with me looking for partners? Did you forget? I remember even the moles on your dirty ass."
No, Chase. Absolutely not! We were just at the same place having sex. We each had separate partners!"
Right, we just had sex together, no, I mean we had sex but were just in the same place, not that we two did it together. Understand? You get it, right? You understand?"
I've done it with up to five people, but he's only done up to four. I know."
No, that's all from before I met you... After having Pete, I lived well-behaved too!"
Well you can say, if Dane was 20 then Josh was 19.
There were more, but I don't chapter no where Dane was telling Josh that "you got married and all, and I used to think we will always be like this"
