Oh bless you. Being turned down cant be nice at all.
A very good friend of mine has to go without for months and months. Her husband won't have sex while she is pregnant, end of. He just won't do it. He doesn't feel it's safe no matter the advice he gets and he just doesn't feel comfortable with it.
Maybe your hubby is just dealing with a few feelings and trying to sort it in his own time. My other half is a huge worrier and always wants to keep it from me so it doesn't affect me but after all the years, he is learning to just be open when he's not feeling great. Maybe your husband just really wasn't in the mood? We don't like them complaining when we're not up for it, so although rejection is hard, we should allow them to say no, just as we expect, rightly, to be able to.
