When it comes to flirting, Aries is direct and aggressive. If you want to kiss him, do not ask for permission- just does it. Arians like compliments, they want to hear that they are the most attractive people on earth. But, feel free to confront them, a good argument is a true aphrodisiac for them.
If you want to win Leo’s heart, that will be a real battle. S/he has already forgotten that s/he spent a night with you. Messages you send in order to continue dating, s/he will not open, nor reply.
Pisces like to seduce and they never turn on their emotions. Maybe much later, but that's very unlikely. They are very refined, so they make every girl feel like she was the only one. But, that is just a trick they play in order to seduce their partners.
