There is a lot here, to get handle on, with this subject.
As always context is critical.
The word love is contextually unattached. Therefore is useless
The term value connotes an actual identifiable assessment, or range.
i.e. I value you for these reasons.
Sex has two value assessments. Your valuation of yourself and that of your partner.
This is critical to note.
Also critical is that value has to be an objective assessment. The assessment must be based on reality and not social consensus.
You can not just say I have value, or they say I have value. There must be actual value.
I would submit to you that a person can have valueless sex. It is masturbation with another's body.
This would presume that an individual finds sexual release to be a value.
In this scenario, the individual seeking the valueless sex can be celebrating the value of themselves.
So to respond to your question: Does how your partner views sex affect your view of the relationship?
Yes
The answer would be the same for all of the potential partner's views. Another words: Are they rational?
The answer to that will absolutely affect, any potential for, relations.
