sorry to say, but if she has her own site, that would be her official site & not yours. Your siteīs her content & you could say "her first content filmed".
We had similar problems with a few models, many of our models were first time vids too, so thatīs what we promoted the sites as, "(models name) first time porn vids"...
itīll sell better too if you promote it correctly. You took her porn vid virginity
as far as using her content for a site, you can do what you want with the content if youīve got her sig and ID, but just go on the official site, because obviously itīs not as you wonīt be able to continue filming more
