my girfriend is the same way, just doesn't like it so instead we experiment together. masturbation isn't the only way to find out what you do /don't like.
No, you do not have a problem - not at all!
Everyone develops at their own pace. Everyone transitions at their own pace. What you may find stimulating today may be different than what interests you in 5 years. In other words, one's sexuality is constantly changing or evoloving, just as the rest of you is, physically, mentally, psycholigically, spiritually, etc.
Just do what feel good to you, do what feels right. There is no "right and wrong"/ Please do not allow pressure from a boyfriend - it's like you pressuring him to enjoy something that just doesn't interest him! Pressuring a partner, no matter how young or old one is, never is an ingredient for good sex and intimacy.
You guys are young. That's great, it's fun. But be your own person - that's what sexuality is all about - your own expression.
Also: when, how, and where you masturbate is really your business - you don't have to justify it or defend it or perform for anyone but YOU!
Love your body - Be healthy.
Yeah, guys reach their peak in their twenties, women reach their peak in their forties. Where was God's sense of humor in this one?! :D
Lots of girls your age just don't find it the same or as good as with a guy, or so i'm told. My closest female friend actually told me pretty much exactly what you just said, so yeah - perfectly normal.
Although i've heard it gets easier to enjoy yourself as a woman as you get older, apparently. Not an expert, to be fair.
No, you don't have a problem. Everyone's sexuality is a personal thing and no one should ever feel pressured to do anything they don't want to do. If you don't enjoy it, don't do it.
