what's up man, just an FYI that penetration isn't that important. Start off by kissing her lips, neck, ears, boobs, etc. while using your hands to massage her body, legs, head, etc. Slowly tease her, treat her like a goddess, and avoid touching her vagina since that should be the final course. Once teased, you can move onto the vagina, and focus on the clit. The clit is like a tiny penis, so focus your tongue on there while, again, using your hands to massage her body. Take your time, and once you go in to penetrate, keep kissing/massaging her. Try and play with her clit while penetrating, but be gentle! Seriously be gentle lol. You'll learn as you go, but just know that for most girls, foreplay is important.
