dude! you're a good looking guy with a big dick....you shouldn't have to pay for sex!
I'm wondering if you guys actually think like that? If you think that just because you have a huge cock, any woman you encounter is going to want to jump into bed with you, you're so incredibly deluded. lmao Women don't work like that, generally speaking (sure there are some but they are few and far between).
As others have said, avoid the streetwalkers. They're usually drug addicts, practice very little safe sex, and many already have an STD. Some don't, but you're literally in the middle of a crap shoot trying to pick out one that doesn't fit that profile. Plus the cops are always watching them, so you're liable to end up in the middle of a bust in many cities.
There are plenty of ad sites for escorts on the web. Go to one of those, select your city, make a call and set up an appointment. As the person who pointed out what Jack Nicholson had to say on the subject, you're paying for them to go away when you're done. You're guaranteed to get laid. Plus, escorts are professionals and they know what they're doing in bed, and most know how to handle a larger cock! They all are tested routinely as well, so you run very little risk of catching something.
Two of the best sites to find escorts are The Erotic Review and Bigdoggie dot net. You can do searches in your city and find providers with good reviews and go from there. On both of them you have to pay to be able to see the detailed reviews, but even with the free accounts, you can get an idea of who to see and who to avoid.
If you use Craigslist or Backpage, watch out because there are a lot of bait-and-switches on those sites. If you find someone that interests you on one of those sites, find them on TER or BD and make sure they're legitimate.
I actually do escort work, so if you have any questions about how it all works, PM me and I'll try to help you out.
