Sexsomniac

So I have sexsomnia and my husband is fine with this its not an every day thing and usually just makes me masturbate In my sleep, I don't share my bed with anyone else so it's never been a problem.
That brings me to my confession which I have to share just to get it off my chest. I went to stay with a friend and she knows about my issue but said it'll be fine for us to share her bed as we have before with no issues. Anyway 1st night I woke up masturbating naked and we laughed about it and went back to sleep with no further issues. The morning after the 2nd night though I thought all was good until my friend told me she woke up to me fingering her and myself until we came but she said it was fine the 3rd night she suggested we try something to see if it helped and with that she started playing with me then started going down on me avenue sticking a finger in my bum which felt weird but good and ended with some intense lesbian sex and that night I woke up cumin on my friends leg so she decided it was only fair I made her cum aswell.
I was at her house for almost 2 weeks and we ended up having a lot of sex even doing things I'd never done with my husband and now I feel really guilty because I loved it and want to do it more but I don't want to include my husband or let him do stuff with others. I actually kind of want to just keep him for the boring standard sex and do all the fun stuff with woman and I know that makes me a really bad person.
