If I consider it properly and not just think about who I've been beating it to for the last 2/3 years but the longest and most consistently, it's bound to be one of three.
Pamela Anderson was responsible for my first sexual arousal, first touching myself, first orgasm and at least all of my first 5-10 wanks, I would say. She was an obsession for a long time, for as long as I've known what my cock was for, and I still very occasionally knock one out to her. She's a constant. (Honourable mention for similar duration would probably be Carmen Electra).
Kelly Brook, I've been jerking off to since I first saw her in 1997 and she's never been off my radar. I doubt I've ever gone a couple of months or so, even with so many choices, without stroking to Kel. Within the last week, in fact.
Jenna Jameson was the first pornstar I knew by name when I was first discovering hardcore and I've lost buckets to her, and despite every year bringing new fresh and hot pornstars, I'll always revisit Jenna from time to time. Honourable mentions : Jill Kelly, Tera Patrick, Briana Banks.
In terms of sheer numbers.... actually, there's a very good chance it's Kelly. There's never been a time I've not been jerking off to her latest photos, consistently, for 18 years.
