How do i know when to stop kissing a girl? I dunno if I'm overdoing it and she wants to finish already or something.. plus I dunno if I'm doing anything right.. if I should kiss normally or french kiss.. whatever.. basically my question is when do I stop kissing. And also how long should my kiss usually be.. if we're like in the park or just any public place like that should i deeply french kiss her or is that inappropriate? arite i know its a lot of questions but please just help me. thank you.
