how do I pay and pay on the website
You don't pay for cuddles through this site, I don't believe. You book through this site. Individual pros will list in their profiles what payment methods they accept (cash, Venmo, etc.) Payment is due at the start of a session.
If you hire a Pro Cuddler from this site, she should explain the process to you. Basically you use the booking panel on her profile to schedule. It’s not confirmed until she agrees, she must officially respond, you must agree also After screening with each other, you make your arrangements, work out details. You must pay her directly before the session begins. Again, be very clear and work all of this out before you meet. She will have her own requirements. You exchange yours with her in advance.
