Have you tried to show him the BDSM site, maybe you can try and see how he reacts. It may solve your problem.
I did have him read some of the stories i liked on here and same reaction: not much to say but a bulge in his pants....lol. So i dont know if he liked the BDSM stuff or just the fucking. But maybe i will try again. I just dont want to be bugging him or anything
