This is how social life starts, dont wanna spoil it but its full of wonderful and confusing stuff. If i may i suggest you to try some rejection selftherapy where you walk to random spots u think will say no, who knows maybe u get a few yeses u thought were impossible. As u long as u are good and nice and ur intentions are pure, and if you are willing to correct the mistakes u will make in the future, to learn from them as much as possible, u will come far. Just dont forget to have fun.
