I am a man in my 30s and ever since I can remember I prefer older women. No Grannies or anything like that but women in their 40s. Anyway, over a year or so used several sites including Cougarlife, Cougars69, Cougarhangout, Milfaholic and many, many more.
I had multiple contacts with real women on Cougarlife and Cougars69 but I was very frustrated with the other sites. Mostly fake profiles, almost impossible to meet anyone.
Even Cougarlife and Cougars69 are not perfect, I think they're still the only real sites out there.
