Hello, I have tried POF and continue to try

there are some sexually motivated individuals on there but there are some ok guys too. You just have to weed them out! You can set your profile to block anyone from contacting you who has set their looking for as 'intimate encounter'. Once I had done that, I stopped getting the dodgy messages. You may have already done that.
The way I see it is, I consider myselfto be a genuine person on there, looking to meet a nice bloke so if I am on there and you are on there, there have to be men like us on there too!!
