I spent 10 days in DR last year - on the north shore. Most of the tourist traffic is in the south, but I prefer the slower lifestyle in the north - less traffic means you can be the Big Fish in the small pond.
Most of the Chica's you will meet in the DR will be either Dominican or Haitian. So as long as you likes LBFM's you can order light or dark chocolate for your snacks. Pricing is relatively low compared to US rates for both SB's and Pros (or freelance/semi-pros); around $40 to $80 per session (2,000 to 4,000 DOP) depending on factors like time, hotness, and services requested.
Expect to wear a hat for FS, though BBBJ's are fairly common. Bring your own blue pills (if needed) and covers and don't trust local Vitamin V or Jimmy Hat vendors.
Find a local shop that will provide US to DOP money exchange for low rates. So much better than official Cambio booths or airport ATM's.
Some basic Spanish will go a long way with the Chica's. Use Google Translate for more complex issues. The DR population that caters to tourists (especially Westerners) will be helpful and patient while you stumble through translation issues. Tip well and tip often. A "big" tip of 100 DOP (Dominican Pesos) is about $2 US. But beware of crowds in tourist areas. Watch out for bump and grab thieves. And don't leave valuables like your phone or wallet on a table top where someone will grab it when you are distracted.
Wear masks and be aware of local safety protocols. You DO NOT want to have an argument with locals - as they will gang up on any Westerner who is an asshole and the cops will always side with the locals. It will be VERY expensive (Thousands in USD) to buy your way out of LE actions.
Finally, do not rent ANY vehicles. No cars and definitely no motor bikes. You will be ripped off and get charged for damage you didn't cause and probably doesn't exist. Take "moto conchos" (Motorbike taxis) for short distances, and Uber for longer rides - confirm the price with the Uber driver before you get in. Taxis at the airport are usually honest. In other places, not as much. But no matter the type, origin or destination of the ride service make sure to ask for and negotiate price before you sit on the bike or get in the car.
If you just want to shoot fish in a barrel (i.e.: Hot pros between 18-30 yrs old for $40/hr I have pics! No, I'm not sharing.), go to Blackbeards resort on the north side, near Sosua. They just reopened and are fully operational even under nighttime curfew. PM if you want details and I can refer you to right contacts.
