Society likes to put labels on people.
For example, you are a 'lover', you are a 'girlfriend', you are a 'wife', you are a 'mother'.
With each of them we are socially conditioned to attach different mindsets and identities.
We generally do not think of a 'wife' as hot or sexy. We don't tend to identify the 'mother' of our children with hot passionate sex.
Because of this it inhibits the passion we feel towards our women. And the passion in our relationships.
These identities don't allow us to look at a woman in the same way as when we first met her. When we had a raw physical attraction towards her.
Or towards a woman that we don't know (some men like to fantasize about strippers, models or other 'hot' women).
Throw these labels and your ideas of these identities away!
Don't imprison your natural sex drive or restrict your behaviors because of these labels. You will demote your sex life, and as a consequence, your relationship too.
To realize the full potential of your relationships, you MUST be as sexual with your 'girlfriend', or your 'wife' and the 'mother' of your children as you would with a woman when you first met. Or the women you have fantasized about.
