Like Paris I blog about what I've been up to. The other week I blogged about going to Hard Rock Hell, as I'm a big rock/metal fan. I'm also into the fetish scene, 40's/50's vintage scene and burlesque scene, so I'm usually up to something one weekend or another. Guys love it when I put up saucy pics of me in my fully fashioned stockings and suspenders in public places, or what I've been up to at a fetish club etc. I've had quite a few comments from them when they've come to see me.
If I've had a couple of quiet weeks, then I might write my own review of a movie I've seen or book I've read. Also I occasionally write about what goes on in the sex industry, such as when Rhona Grant was trying to get a bill passed in Scotland to criminalise clients who see prostitutes. I think writing about things like that now and again, makes guys aware what really going on in the industry and how it can affect them and us.
Putting up a few saucy pics throughout your blog will certainly keep them interested.
