Brief Answer:
Setting a dialogue will be most proper

Detailed Answer:
Hello,
Thanks for using healthcaremagic.

I read your query and understand your concerns.

First of all I like to make it clear that body compatibility does not mean you are sexually compatible or vise versa. From my experience with couples I have experience that people have different needs as social level as well as individual level. I mean to say that you may be meeting his eye but he may have some other thoughts about how a partner should react in bed and that may be the reason that he is not satisfied sexually.

If he is so from your initial days than there is some issue of sexual compatibility. In case the problem is recent following the child loss he may be having guilt issues preventing him fully to enjoy the act.

Rather than thinking otherwise about sexual compatibility or anything else it is important to open a dialogue with him about his preferred partner or another issues in his mind.

I must assure you that with proper dialogue you will be able to know what is wrong in a perfect relationship and that can be corrected in majority of issues. In case you are unable to do so it will be appropriate to seek help of a relationship expert in your city.

I hope this helps you.
If you have more questions feel free to write back to me.
Thanks and regards.
