If Francois Sagat wanted to make a film with me I'd be there in a second, haha!
But otherwise...well, think about whether you want to make a career out of it. If you do, then you can earn well and have a great time. If you only intend to do it as a one-off then I'd probably advise against it - as others have said, it will be around forever and people who you may not want to see it will end up seeing it.
I think porn is definitely fine to get into if you're sure it's what you want to do and you have weighed up the pros and cons. I could never criticise anyone who wants to do porn, since as a porn consumer that would make me a huge hypocrite. If you can handle the industry then I see nothing wrong with it.
That said, DON'T work for bareback studios or any company that does not insist everyone wear condoms. Work for legit studios like Titan, Raging Stallion, Falcon - where condoms are mandatory. Safe sex!!
