Being a husband , Am telling you all Forget about Body. Focus on how well you can connect with women/wife at mental level first. See her responses, verbal/non verbal cues - pay close attention . Create great impression - of course not fake. Be generous and care-giver. Show genuine curiosity and interest in her hobbies and likes.
Let her reciprocate and develop interest and likeability - it takes time.
Once you are in her good books things becomes smooth and easy.
Patience is magical - get a taste of it once.
Give it try and let me know your comments !
Take care
