<human>: Can you give me a shortened version of the text?

We have been together for one beautiful year and love each other very much. I happened to find porn featuring women with penises on his computer. It was shocking and I'll admit my stomach sank a little bit. Everything in our relationship has been carrying on as normal. Our sex life has always been very active. I love this man, and I won't discount the fact  that my lack of understanding could be due to me never having explored masturbation/porn very much.

I don't want to jump to any conclusions, and I don't know what it says about me that I was so initially uncomfortable about it. The problem is that I just don't know if it means anything. I've always tried to give him a lot of privacy regarding masturbation and porn. I figure that unless it starts affecting our sex life, it's obviously harmless, and everyone is entitled to their secrets.

I didn't want to ask any of my friends for advice because I'm sure they've never been in this predicament, and I don't want to embarrass him by telling people that know him. I read around online and found a shocking number of girls that discovered the same thing, asking for clues. The responses vary so greatly, just as I would expect them to here. 

Of course, none of you know him like I do. He's had a long past with porn, including a period during his younger years where his strictly Mormon parents caught him and sent him to therapy over it. He is not Mormon anymore, and I've been trying to help encourage his sexual exploration as best I can. But this is clearly something out of my area of expertise.
<bot>: Discovered that my boyfriend of a year watches some transsexual porn, and I don't know what it means. I guess what I'm asking/prompting here is.. What does transsexual porn mean to you?
