Tip for guys

Guys, if you want to impress a girl, here is a tip for you. Apparently one of the ways to impress is to have proper bed sheets and proper towels. To be honest, I do not know what exactly proper mean, but I would assume that it should be something soft and expensive. For example if you can put your hands on sheets made of Egyptian cotton, it should probably do the job.
Thinking it over, I must admit that this tip has no solid ground. Does it really matter if a guy has or not proper bed sheets? It seems that there are three situations when bed sheets have a role in relations.
First, it is the introduction. Till today I have assumed that by the time the couple reaches that stage in the relations when the girl is introduced to the bed sheets the girl must be already impressed and charmed. Which is probably true.
Second, it is the next morning when you wake up and both of you, admittedly or not, think if the experience was worth it and if it should be repeated. At this situation all counts. If the guy fall asleep first and snored all night then probably only the great sheets can make any difference. Therefore if the girl comes again, it would probably because of the sheets rather than of the guy. This allows us to assume that if the guy have had bad sheets and the girl came again, then probably the guy is the reason. Pure logic it is.
Third situation is when the couple goes out for a while and the first excitement disappears. At this stage the couple can probably talk it over and the girl can pick up the right sheets to emphasize the sleeping enjoyment.
Unfortunately, the source of the tip is reliable and it would probably impress a girl if the guy has proper bed sheets. This raises a question in my head: What is the probability that the man who goes shopping for a proper bed sheets and knows how to do it would be part of the straight community? :)
