Some would say John Glen is a bit of a boob 
"Did anybody watch the film not knowing what Dalton looked like and get fooled?"
Considering he was on the movie poster it would be difficult to be fooled (unless they did like on one of the OHMSS posters , where Bonds face was obscured)
"DaltonBond does not get laid much"
He prolly slept with them even though it wasn't implied on screen
