My opinion is in a proper long term relationshiop ( LTR ), where there is love the right things will happen. Maybe not in the exact frequency we want them, but they will happen.
What are you saying? That if it's a good long-term relationship, then sex at some frequency will be guaranteed to happen? And if sex doesn't happen, does that not make it "not a good relationship"? Which means you'd always be right, just by definition alone. So I'm not sure what you're saying.
