Are you referring to being fingered strictly by others, or yourself, too? Do you feel sexual desire? Attraction to others?
When you say no pleasure - do you mean you haven't had an orgasm, or do you mean you don't like it, or it's painful, or it's just kinda blah?
For me, at first, I wondered why people wanted to keep having sex. No offense to teen boys, but they aren't nearly as good at it as they think they are (and I'm sure it's the same for teen girls), and it takes time to learn.
Some women don't get that much pleasure from being fingered, or maybe it's the way that you're being fingered. Have you tried clitoral stimulation? Some women really prefer that over fingering.
There's no right or wrong answer here. You'll learn what you like and don't like, but don't expect it all to be like romantic sex scenes or porn (which is all fake). If your partner isn't doing what you like, or is doing something you don't like, communicate that nicely. (Communication makes sex so much better.)
So why aren't you enjoying it, and if you aren't enjoying it, why are you still having it?
