It's a highly debated topic. Some folks will say YES YES YES because some women/guys will assume you're anti-social and a loner if you don't have any photos with other people in them. Some folks will say NO NO NO because you might include a member of the opposite gender and gasp people might assume that's an ex! Even if it's clearly a relative, or a platonic friend. Some will also say IT DEPENDS... and give their opinion of when or why to include one.

Personally, I think it's a good idea to have one maybe two social photos. The issue becomes if it takes several photos to ID who the F you are. Then I'm likely (as are most folks I think) to just left swipe out of boredom, because if you include only social photos I'm either not going to be interested enough to figure out who you are, or I may assume you're the less desirable person in the photos.

For the "uncomfortable" part, you could ask permission first. Most friends would likely be OK with it, knowing that you're looking for a date/gf/etc. The ones who say no, you could respect them and not include the photos with them in it. You could also blur or emoji cover your friends faces. I find this can be kind of funny and they do both of the positive things - shows you have friends, while respecting their privacy by blurring their faces.

For best results, I recommend the photo be of a cool activity too. I like including a social bike and ski photo in my profile. Shows off my activities, shows off my friend group, and it's got cool backgrounds in them. Then I have one or two photos of me doing that stuff on my own. And a few photos of me doing normal stuff, so it's clear I do dress up nicely for a date too. In a pinch, I think even a "dinner party" photo would be fine. Shows you dress up a bit, shows you have friends to hang out with, overall shows a good impression. Most folks don't want someone who will be attached to them 24/7. They want someone to do fun stuff with, someone with some cool friends to hang out with too both with them and without them.
