It does already - I looked it up. It even applies to interstate lines with varied age of consent - although it is a bit more intent based and grayer. For example - going from say California - an 18 age of consent state to sleep with a 16 year old in Nevada is illegal sex tourism. Likewise bringing a 16 year old from California to Nevada to try to evade the age of consent is illegal. But going to Nevada from California and sleeping with a 16 year old while not there for that purpose (say on a business trip) would be legal.
