I agree with what's been said so far - wait til you feel ready and aren't scared.
But I want to add something based on your specific fear of taking someone else's virginity or being a fraud about sex.
While you are in high school, people talk about virginity or being virgins or "losing virginity" as though this is: (1) easily defined by a clear act or set of sexual acts; and (2) significant or important, as opposed to any other time you'll have sex or engage in sexual acts.
The reality is that neither of these things is true. There is no one sexual act that defines losing virginity (which traditionally meant penis in vagina sex). And the truth is, while the first time you engage in any of a number of sex acts can have significance, it doesn't have to, and as you get older, no one will really care what age it happens at & what kind of experience it was (spoiler alert: people are not born "good" at sex, you learn what is good by practice and experience).
So there is no reason to be afraid of 'taking someone's virginity' because you used fingers, a mouth or a strap on - or someone did the same to you. And there is no reason to feel like you are a fraud or a fake becaue of your equipment, because that comes from an inaccurate and outdated concept of what sex even is (seeing as it can have no penises, two penises, etc.).
There *is* reason to feel afraid, uncomfortable or not ready to have sex. Sex as portayed in media - movies, tv, books, etc. - is not accurate. It's not that it is over-rated, it's that you have been flat out lied to about what sex is or is like. It is messy and kinda weird and doesn't have a specific progression of acts you have to follow and it can feel really great and/or be something very intimate to share with another person (or not). It also has a host of risks that come from it too, from the physical (STIs) to the emotional (sex occurs because of and produces chemical reactions in your body that come with feelings you may not be ready for or happy about). Of all the risks, though, the thought that you will ruin someone's virginity losing experience somehow, rates low to non-existant.
