If it makes you uncomfortable, there's nothing wrong with asking him to untag the photo. Of course you know he dated other girls in the past, but not wanting to see his hands all over someone else every time you go to his Facebook page isn't unreasonable. And really, it's not that hard for him to untag it if it's going to avoid drama. It's not like you're asking him to delete all his past photos forever. You just don't want it in your face all the time. Nothing wrong with that.

Back in his pictures from 2005 isn't exactly right in her face though! Unless he doesn't have many pictures you'd have to do a bunch of scrolling.
Maybe you'll have to be honest with yourself, is it the pictures that bother you or the fact that there was this chick he had this relationship with before you? It's fair enough to want the picture gone but maybe take the time to think about how that was in 7 years ago and you're his girlfriend now!
Had the same thing happen to me but my guy had multiple pics on Facebook with multiple ex's. I tolerated it for a while but eventually I told him while I acknowledge he has a past I really felt it was disrespectful for him to keep those pics posted on Facebook. If he wanted to keep them on his computer, fine, but to keep them on a social network was like a slap in the face. About a week and two fights later they all came down, and he also defriended his latest ex, who he broke up with about two weeks before we started dating. Don't ignore something that bothers you, even if it's small. It'll just grow and fester until it's taken care of.
At least they're out there and you know it. My bf keeps naked picks of multiple ex's on his cell phone and jacks off to them when I'm sick. And he told me this once when I had the flu, when I asked about it later he denied it, and I don't have the heart to snoop through his phone.
wtf........
WOW I don't know who you guys are dating! There's no way in hell i would ever be happy with my boyfriend keeping naked ex's pictures on his phone, or pictures of them both on his computer! That definitely shows an emotional attachment is still there and is really disrespectful! On social networking though, its usally other people that have put them up there and you can't expect them to go through every aspect of there online life and defriend, untag or delete pictures because you feel insecure. My boyfriend is still friend with all his exs on facebook.We live in a small town so we're regularly in the same building as them!
