Asking on behalf of a friend - When you're pregnant, I think it's inevitable that a woman feels less attractive. How do you ensure the chemistry between your husband and you is still alive?

Nothing can be ensured. As you've said, it's chemistry, so what is sexy is determined by both parties in the relationship. Although most pregnant women feel down about their changing bodies, there are pregnant women who embrace the changes and feel sexier than before and it radiates outwards. Confidence is sexy.
