There are a few ways you can monetize your site:
1. Affiliate Marketing: Since you mentioned you have enough traffic, connecting with companies in the same industry that sell products your customers may be interested in may work out well.
2. Sell ads-Approach companies and see if they would like to advertise on your site.
3. Offer your own products/additional services-In addition to contacting escorts, you can offer other services or products that are geared towards adults.

Hope this was helpful!
