How do you strike up a convo/friendship with a man?
Always my first question because too many folks asking questions like this don't. If a person can't cultivate a platonic friendship, a romantic relationship is beyond their current skill levels. Romantic relationships are hard mode.
Meeting through friends and social groups like sports, clubs, church, whatever, is much better than cold approaches, IMO. I can see a dude display they have social skills and we both have something more than "he/she is pretty" to go on.
Don't have friends and hobbies? Tackle that before worrying about dating. Romantic relationships are like friendships but on expert mode.
Counter-question, how can I make it clear I DO NOT want to be cold-approached by ANYONE while at the beach? Headphones, sunglasses, and my face in a book has not worked.
