Detailed Answer:
Hello Mr. XXXXXXX
Welcome to 'Ask A Doctor' service...

I can understand your concern...

From your description, it seems to be related to mood basically...Please note that mind and body are interrelated to each other...When it comes to intimacy it matters even more to the counterpart (your wife in this regard)...

Another point to note that, during a stressful situation, the body's not prepared for intimacy so as the hormonal and several physical changes (these are the normal physiological process which aid in intimacy)... the same thing's applicable down there too...

So the answer to your question is Yes, it does affect likewise...

Few suggestions to get over this:

-Please focus on foreplay and take it slow and easy (this will take some time but will be immensely helpful in the long run)...

-Perhaps spend some quality time together (go out for a nice evening walk, social gatherings, dinner-nights, movies), this will ease the mind and things will proceed smoothly...

-A brief period of abstinence will be helpful (just spend some quality time together without being physical)...This will actually aid in better intimacy after a while...

-Most importantly, please try to understand your counterpart's psyche (simply don't go for it when she's not feeling it, and no forcing strictly)...

-When she wants to be alone, just give her own space and give it some time...

-If you're recently married then another suggestion is to talk to her best friend/nearest family member (whoever you're familiar with)...This way the message from your side will also be communicated to her end...give it some time and see if she wants to discuss about it (if at all, then don't hesitate and talk about it frankly, it'll clear the things in a much better fashion)...

In my suggestion, with time and practice, things will be much easier...

Please let me know if I can assist you further...

Take Care
Kind Regards
