Irritating? Yeah, probably not. Another reason to say no? Probably so.
We don't have a picture on our profile that is older than 10-months. Generally our lead picture...OK, her lead picture is less than 3-weeks old. Before I use the age old saying of everyone judges, I'll limit it to only ourselves and yes, we judge couples. If you've had the same picture(s) on your profile in the approximately 3-4 years we've been on the site, it's almost an automatic no. Right or wrong it tells us you've given up. You've lost the creativity to grow in your sexual adventure. We actually age. We don't look like we did five years ago, why would people continue to use a dated pictures to attract other couples?
We would be embarrassed to actually meet a new couple and recognize that look on their face saying...ohhh my that's not the people that were in the pictures. But then again, we are actually here to meet people. Our working assumption is that the more dated the picture(s) the less inclined they are to actually want to meet. We can almost draw a straight line between those who have dated pictures and those who have ghosted us. Wonder why that is? :)
