((hugs)) I agree with the PPs here, but I just wanted to add:
With everything going on in your lives right now, don't beat yourself up about the bedroom situation. Stress will just shut down your libido. The important thing here is to have a honest, non-confrontational, honest discussion about that. Are you actually feeling unsatisfied? Or do you just think that you're supposed to be doing it like rabbits and so you feel like you're not "doing marriage right?" How many times a week/month would be enough to make you feel loved, satisfied, and connected as man and wife? What other things outside of actual intercourse are important to you to help you feel loved, satisfied and connected? (Meaningful sex is more than just the biological function). Answer these questions for yourselves, then talk about them together.
This is a really important part of your connection to each other, so definitely make it a priority to meet each other's needs - but don't put pressure on yourself to meet some sort of quota that neither of you really need. Be honest, and compromise if things are drastically different in your needs.
My husband and I are still really new newlyweds - unfortunately we had job loss situations right after the wedding so we are also dealing with the effects it has had on our relationship. I definitely have a higher drive than my husband, but the depression has been crippling to him. We have had to make compromises, and counseling has helped me to realize how to be understanding and identify my needs that he can meet as my husband, and what needs I can handle myself (if necessary...sry TMI but it's true). It has helped him to realize how important it is for me to feel loved and secure that we have that physical connection.
Sorry for the book, but I just want you to know that you guys are SO not alone and you WILL get through this. Don't be afraid to ask for help :) Also, given all that is happening, you may want to think about your individual mental health - could it be a factor? For my husband, that was a big Yes. Identifying his depression and getting help for it has been a huge help for both of us.
Hang in there :)
