I'm almost 50, my boyfriend same age. I have no issues that he has pictures of past loves,, I have no issue if he finds a woman attractive. However, while we have been dating I noticed he had downloaded & saved pictures for several months of a 25 year old "friend" a woman he had a fling with, ex girlfriend S and woman that are his Facebook friends I don't know.
Some pictures he saved were several years old so he had to spend a lot of time searching. He said its no big deal, I'm immature and he cant recall why he did it
