I've lived in states that are about a quarter of the size of the EU, but with less than 1% of the population
Besides Alaska there aren't multiple states that would fit that description tho. Texas is about one-sixth of the size of the EU but has a huge population, Montana's the 4th biggest state (after AK/TX/CA) but around one-twelfth the EU's size
You're probably being hyperbolic or smth this is just me being pedantic lmao I have OCD
Yeah stuff like mile high club is legaler than you think, one time I took weed gummies with my ex-boyfriend before a flight which gave us the brilliant idea to go to the first class bathroom together at 4am to "make out," he gave me a blowjob and that was that. It's literally only illegal if you're caught in the act and something like that you physically can't be, just don't make noise
Not recommending or condoning it we're just fucking stupid stoner college kids. If someone saw us coming out, we pass as two straight guys so we thought we'd say something like "we're just friends who needed somewhere private to talk about something personal" 
In the off chance someone presses you can just pull a limited hangout and say this is the first time you're seeing each other in a while and you wanted to kiss, there's literally no way they can know you did more
