shy but secretly kinky. help.

my husband and I have been together for 5 years and our sex life is pretty fucking boring. I enjoy time alone when I can watch porn and I have watch and been turned on by some pretty freaky stuff. I like watching pee fetish stuff and also solo males that can "self fuck" along with a bunch of other strange things. idk if this is my escape from our boring sex life or what but I need some ideas for when we are in the bedroom that can spice things up but won't scare him away. I am also really shy..even after 5 years with him I still have a hard time telling him what I want. i made "joking" comments about peeing on him and finally when we were in a hotel on vacation about a month ago he let me pee on his dick which really turned me on but I still had a hard time with it because I am so shy. I need to come out of my shell a little bevause I know he is just as bored with our sex as I am. it also doesn't help that we have been ttc for a year and a half and sex seem like a duty now. ugh. tips, advise, anything welcome.
