I think it is generally overlooked.
Look: boy and girl, slowly leak air through the day and need each others help to get inflated to capacity. If one gets punctured, there is one who can help and is trustworthy enough. That thing of sharing a secret. Well, the list can be continued. Just my point is that erotic, sexual side of inflation is heavily exploited, while romantic is not. Agree?
I agree, and to that end wrote a couple of i hope romantic stories about it which are in the Library:
