In theory that should be true, but many marriages are not based on love.
To clear up any confusion, while many use "making love" as just a euphemism for sex others use it to describe passionate sex between two people who are in love with each other, which is made more confusing by the fact that so many don't know what romantic love truly is. As opposed to "just sex" which can still be fun of course, but no matter what still misses that little-bit of pizzazz that comes with proper love-making.
AV1611VET here seems to be under the impression that a husband and wife have to be in love and/or have to put the effort into sex that would turn it into love-making rather then...shall we say "stress relief".
Or he could just be an idiot who thinks making love is just sex between a couple married in the eyes of god or something.
