I will not judge you at all my lovely.
You seem embarrassed about this? Please don't feel that way, I know all too well how you must be feeling as I have felt exactly the same.
When I turned 17, I was still a virgin and I remember being very embarrassed, clueless and I had no one that I dared talking to about the way I was feeling.
At that time, all of my immediate friends had lost their virginity and were having sex. I faced a lot of peer pressure and I felt as though I was weird and was being labelled an outcast because I was still a virgin.
I eventually gave in to peer pressure a few weeks later and stupidly lost my virginity to a local idiot boy in a cold and wet field. It was absolutely awful and I still to this day, 14 years later, regret it.
As I've aged and matured into a sexually experienced woman, I've come to learn the importance of sex being special, intimate and experiencing it with someone who you trust and have a connection with.
Fair enough, some people seek out a casual fuck because they think that it's great and pleasuring. I used to do the same thing and have various one night stands and casual fucking, but my experiences were mostly shit and I realised that I only did it because I wanted a cheap thrill and ego/confidence boost.
I'm not saying that once you become sexually active, not to have casual sex. You may decide that that's what you want to do and there's nothing wrong with it at all, but my personal opinion is that the best, most passionate sex that you can experience, is when you find someone who you have a bond and attachment with.
Take it from me, don't be self conscious or ashamed of yourself. I've been there hun and I promise you that things will get much easier once you respect yourself and mature.
I really hope you can overcome your situation and lose your virginity to the right girl and in the right way. You'll be proud of yourself once you do that.
Good luck.
P.s I'm just an inbox away if you need to talk x
