I finally found a girlfriend I liked, but I was so insecure about sex that I gave up on myself. Her friend saw me like that and gently taught me sex techniques! Thanks to her help, I finally succeeded in having sex with my girlfriend! "Have you learned the techniques I taught you? Let me check for you." She not only practiced beforehand but also kept me informed afterwards—she's such a thoughtful friend. Look at my first time having sex with my girlfriend; I've been completely transformed!
