Hey Joe;
On the off chance that you end up in KK alone, there is a new gay spa that recently opened here. It is located on Soi Bankok 14. You can tell a taxi that it is near Northeastern University - or you can use Uber. Just type in that address. The specific address, I believe, is 404/64 Soi Bankok 14. Name is Aspara Spa. 1500 Baht all inclusive fee - Loads of young guys on offer, as this is a university town after all. Just thought I would throw that info out there since you might be here a few days. Cheers -
