Like others have stated, I think it is an incredibly personal thing. And much like regular sex within the confines of a relationship, sometimes you want to, and sometimes you just aren't in the mood. When we are young, sometimes we like things a bit racier. Or maybe we start of time, and get racier as we get older. lol. I think that minds can change, and your perception of the world around you can change. If you have any doubts at ALL as to wether you should, wait a while. Obviously some part of it is bothering you and really, because it is such a sensitive situation i think if there is any doubt at all it should be avoided until you feel sure. You can always change your mind in the future but you can't change what has already happened right?

As to wether or not it is inherently wrong or bad - I dont think it is either. As stated, I think it is something that only some people should engage in, and it is not for everyone. I think it can be a special experience for a couple to share sexuality with another, but I also think it is just as special to share that only with each other.

The point of this whole thing is that you need to be sure. I say explain to your husband the misgivings you are having, and maybe try to explain if you can what has changed for you so that he can understand.

I wish you luck though in whatever you choose to go with
