I'm sorry you've tried new things and felt "degraded". If that's the case, then you need to go in another direction. Now, if it's just feeling "ashamed" because you're exploring new things sexually with your husband outside of what we've been told the "norm" is, well then good for you for trying, and there is NOTHING to be ashamed about. Point blank, if you and your husband do things that feel good to one or both of you, and you are both okay with it, and it does not involve others, then GO FOR IT, and do not feel ashamed! "Dirty" should be defined by what you and your husband find acceptable. Not by some "societal norm" or "religious upbringing" that says things or acts are "evil". If both of you enjoy anal, then by all means continue it without remorse or regret. There is NOTHING to feel ashamed about when you're participating in in consenting sex with a monogomous, willing and faithful partner.
Sounds like there's a trust issue here. Not a "cheating" trust issue, but a "him taking things too far" trust issue. Establish a "safe word". If he starts getting carried away (I've done it a time or two because I was "in the moment" and thought she'd like it), then you need to have a safe word where he knows...KNOWS that this is not just an obligatory "No, I feel dirty and don't want you to think I want you to continue, but it feels OH SO GOOD and I really want you to continue" type of thing, but it is in fact something you're completely uncomfortable with and it is time to stop what he is doing. The "safe word" is a no crap, STOP what you're doing signal. My W and I can get carried away. Many times, just because it's "dirty" or "shameful", she'll throw out the obligatory "no" to me. I know, more often than not, this is her subconcious speaking. I'll typically, usally always continue. That is until she says "safe word". If it is really something she does not want she'll say "ok, really no...SAFE WORD!!!" (we don't have a "safe word". Our safe word is "safe word". When she says "safe word" then I stop immediately and we re-group. As a result, she trusts me to stop if I'm crossing a line she doesn't want crossed, and confident I'll continue right up until that point if she desires. Trust is key. When "safe word" is spoken, there is no leway. He must STOP. When you're confident in that, and that he will, all this "dirty" stuff is not so bad. It's the whole "plausible deniability" thing. You can tell him "no", even when you mean "yes". You get to be unsure about what you're doing, voice that, yet still have an instant "shut down" signal when it truly is not what you want.
Establish a safe word between you and him. You both must abide by it. Outside of that, if it's good for the both of you, forget about how it feels "dirty" or "shameful". Dirty or shameful is one thing, and can feel really good. Wrong is another, and that's why you need a safe word.
But, to answer your question...you don't need to replace the anal stuff for more "clean" things if you both enjoy it. Consider yourselves both lucky. As for new, a little less kinky things to try...oh, I can think of a hundred or so. BJ or him going down on you in the park, a parking lot, or on the freeway. Bring a vibrator or dildo into the bedroom. Talk dirty to each other. I mean, honest communication type dirty. Wait until you're deeply into the throws of passion, and ask him "what are you thinking about" or "how does it feel inside of me"...."tell me how it feels inside of me"...that type of thing. Get more vocal with him. For some reason a good number of women just hate to say when they're going to orgasm. Change that up. Tell him "oh my god, you feel so good inside of me. I'm going to come baby...come with me please!!!!". Some passionate "dirty talk" can go a long way.
I'll tell you what I told my W when she felt a little ashamed about things we did that she thought was "dirty". Stop it. It is JUST SEX. That's it. It's only SEX. That is by no means meant to minimize what sex is between two loving and committed people (because the connection of "just having sex" can be so incredible), but people have been having sex for ages! We all want it. We all desire the BEST SEX we can have, especially with a loving partner. It is of the utmost of importance and significance with a committed parter. BUT, it is just a physical act. It is just sex! It is the essence of us as humans. We love it. Enjoy it to its fullest, and don't make more out of it than what it is...an incredibly bonding experience between two people who love and trust each other.
