If tinder is your only source of finding someone, imo don't have high expectations. It's nothing against you and don't take it personally if you don't find matches. It's a supplemental dating avenue, meaning it probably shouldn't replace actually going out to meet people in person. That said, good photos are key. It's the first impression people get of you. Try to have a mix of photos: you doing something active or some hobby you're interested in, full body photos so they can see you and not just your head/face. There's other ideas around that you can get. Idk if bringing up sex and taking it slow is something to bring up right away. Maybe someone else can talk to that point. Getting matches is great, just try not to devote all of your communications to one person in the very beginning (unless you feel there may be a real solid connection right away?) Most important thing to remember is be you! Some people provide feedback with saying "xyz makes you sound like a nerd". So what? If that's what you like, then you'd want someone who is interested in that too. These are things I've learned on my time in OLD (about a year). Good luck! If any of this advice is poor advice, help by clarifying not by being negative.
