It sounds like the pressure your husband's putting on you in order to get there is making things worse. I had a problem like that with an old bf of mine... he would even start getting impatient if I took too long. :/ It may "bruise his ego" a bit, but I'd suggest talking to him and asking him to back off on the expectations like that so you can relax and enjoy it. If he wants you to get there, he (and you!) have to put you first in solving the problem.

The more you stress, the harder it will be.
