Should I have sex?

So I’m a 21 year old virgin and my sex drive has been through the roof lately. I’m a virgin not because I haven’t had the opportunity to have sex lol but I turn guys down because I’ve just had this fear of getting pregnant. I always told myself when I graduate college then I think it’s the right time because I now have somewhat of a job security and if I do end up getting pregnant I’ll be able to take care of my child. So now that I’m graduated I still feel worried for some odd reason but at the same time I’m just craving to get some. On top of that, I am super close with my parents and I just have the thought of them being disappointed in me if I get pregnant or if they find out I’m not a virgin on the back of my mind. I know that’s kinda weird but idk why I worry about that so much. Ughhhh idk what to do lol. I’m just a horny girl and want to experience sex already but I worry too much.
