Yes, a lot of guys relate to what you are saying. They find it harder to ask out attractive people on dating apps.
At the core of the issue is the fear of rejection upon meeting said attractive person on a date. You are so fearful of that, that you allow a conversation with the most attractive of people on dating apps to die out.
As you stated, your way of thinking really isn’t warranted, being that these attractive people swiped right on you.
It’s time that you realize that the way you look at yourself isn’t necessarily how other people see you.
Stop being so fearful about rejection. People are out of your league only when you make them so. No one is perfect. These attractive people have flaws that you cannot see. They know it.
If you keep putting them on a pedestal, you will lose out on opportunities to actually get to know and possibly get into a relationship with someone that you are actually the most attracted to.
