I have recently started to become intimate with a friend I have known for a year. I am quite worried about sex though, because I am a virgin and might not be able to please her or things won't work smoothly enough the first time. I also worry she will leave me if she finds out I am inexperienced and thinks the same, and anyway there is no easy way to bring up the subject out of the blue. I was painfully shy and had zero confidence when younger, and the first girl I kissed was at age 30 (and only after she initiated it)!
I've also had a girlfriend before a few years ago, and we did everything except full sex a few times so I have a small amount of experience. I fell very intimidated by how much experience my friend might have (she has had a 10 year relationship with someone) and don't think I have any chance of being as good as her ex boyfriend in bed.
Is it a bad idea to tell her about my inexperience in the bedroom department?
Talk to her! I have friends who've found themselves having relationships with virgins who were in their late twenties/thirties, and it's not what you know to start with that matters, it's how willing you are to learn.
You'll be totally fine! Really, don't panic. You'll know what to do. I wouldn't give a toss if someone I was seeing was a virgin. I'm interested in the person & just the fact that it's them makes it special even if they're not the most dextrous. When I had sex for the first time it was with someone who was also a virgin and except for the pain (which we're told to expect anyway) it was perfect. Specially because we both wanted to make each other feel good and we laughed and tried different things out. enjoy it!
