So im 19 and about 193 cm, fit for my age but i got a question. Im doing approaches and my typical approach is compliment her, ask her a little about herself and after 20 seconds or 30 seconds i ask for number. I dont really get much success, mostly of them say they got a boyfriend. I did totally probably about 20-30 approaches in my life time but i just started like couple months back now but i wasnt so much consistent as im getting now approaching almost everyday. Now question what can i do to improve my chances? Should I extend conversation to 2-3 minutes or what should i do? I dont tease or flirt during convo, just normal convo
