A big issue is also whether ISPs (and mobile carriers) will work with government/LE and start blocking your access to any and all sites related to the sex industry. Even legal sites like SIN and the brothel owned sites could get blocked, depending on type of blocking filters they use. So, it's not going to matter whether these website are in the USA or abroad, if your internet access is being filtered. Corporate IT departments do it all the time to prevent their employees from accessing adult sites from their work computers.
