Men during sex....

It probably depends on whether or not he loves her already.

physical intimacy can improve emotional intimacy and vice versa.

What is love baby don't hurt me..

I have never felt love while having sex, but I feel it at other times.

Sex is just a man putting themself in a woman so if a male surgeon does surgery on a woman does that mean he "fingered her"?

I think sex can definitely make you feel closer to someone you already love, being such an intimate act.

Especially slow, gentle, passionate sex (properly making love) & the tension, anticipation & then exploration that comes before it.

Sex could never make me love someone but it could heighten an existing feeling

For the duration of the sex yes

Sex is a physical act that may be heightened by one's affection for their partner, but I seriously doubt that sex increases that affection.

No, not for me. Sex neither enhances nor diminishes love.

Of course we do (:
