How do exactly this AV actresses loose their virginity? We European get taught, Japanese is like a sexless country and women loose it with like 21, not with 13 like in Europe. But some actresses start with 18?

One interview of an AV porn actress just showed, she said, she tried hard 100 times to get a role in a movie or in any tv show or weather announcement, nothing worked so she just choosed porn. Like it's any job like any other. Yes.. but not for Japanese ?? (At least this is what Europeans believe about Japanese, since this country isn't for us any 'transgender Thailand ladyboi" country neither a Nepal "16 year old virgins for sale because their families need money")

So can somebody explain to me why giving away the vagina and passing it around for a job career is a very normal thing in Japan? The salary isn't even high it's actually about the FAME.. wtf ?
