Unless you're emotionally hurting someone else then there isn't a problem. You shouldn't care what others will think of you because as long as they're not your mother or your best friend, you don't really value their opinion. You're doing this for you and it's making you feel free and exciting and wild. So why not date more than one person at once? If you're dating more than one person, feel free to post your tips in the thread below. If dating more than one person isn't for you then that's fine but if you ever change your mind, just download Tinder.
