Yes yes and yes. I didn't lose my virginity until I was 19 and then get into a relationship until I was 21 - so a late bloomer by most people's standards - and it truly effected me so much throughout my teen years. Obviously feeling like something is wrong with you but also dealing with people's reactions! Most find it so strange and for some reason they're not afraid to tell you. Feels like you're revealing a shameful secret when admitting in a conversation that you haven't had sex and/or a boyfriend, and the immediate response is "er what? Why? But why though?" Why the duck do you think you potato with eyes
It's so cliché but with the right guy it will not matter - anyone rejecting you on that basis was just looking for a shag anyway. It makes me so sad to think back on all the guys that made me believe I was the one ruining a potential relationship because I was too 'uptight' or 'frigid' to sleep with them in the early stages or worse, too insecure/negative/suspicious of them. It's crazy to think how much they got in my head when looking back they were clearly fuckboys - anyone that ends things or drops you for not putting out is clearly not interested in you at all
