Squirt,

You are right bareback porn in and of itself isnt an extreme niche however, i feel that many of the companies launching bareback porn sites are doing so because they view it as 'extreme' the same way in the straight market throat gagging is viewed as extreme.

Looking over several of the new sites that have been launched in the last 6 months you can clearly see that bareback porn IS being marketed by many companies (gay and straight) as 'extreme'.

Regards,

Lee
