@Njoku Not certainly in that way. Girls can pretend to have "sex" with you (light POV), do lewd things, and generally hint at dirty stuff at all, but that doesn't count as porn. Some image videos may be frankly lesbian (for example, the business yuri's stuff is like queer bait or real lesbian porn with fake couples)., but given that the Japanese perceive this as friendly lewd things between young girls, this is on the border line. This is one of the reasons why Misora will long position herself as a virgin and single straight girl even after a whole catalog of lesbian sex with Akira, by the way.
In any case, although gravure idol's stuff is generally considered fap material, these girls are perceived as idols of the entertainment industry and appear in entertainment shows without any problems, the manga will also refer to this time to time. Many AV-idol begin with this, but this is not a mandatory or anticipated career development.
