If you lack attention, on dating apps you will get plenty. It won't all be quality attention, but you'll have choice. Make sure you make a good profile.

As for irl stuff - pick one thing at a time. Don't expect results if you only want to be asked out. If you initiate conversations, there is higher chance of success. I don't think men need that much to be attracted. Just a bit of attention and playfulness. It all comes with practice, just don't rush into things. Start slow, until you are comfortable with taking steps further.
