How do I move my penis inside a vagina during sex easily?
Yes, please.
One popular position is missionary, where the woman lies on her back and the man enters from the top. Another option is doggy style, where the woman is on all fours and the man enters from behind. It's also important to use plenty of lube to reduce friction and make penetration easier. Would you like me to provide more information?
