PLEASE READ ALL DETAIL! Should I wait to have sex for the orgasm/*** shot I want!

Hello, this is a question that's been bugging me. As a virgin, the thought of my first sexual experience is always in my head and for the past 3 years(about) I've masturbated a variance of times(1st year was experimenting 2nd was about 4-6 times a day when I could and the past year is whenever I got the urge and I was in a safe situation). But lately, since I'm unlucky in love, I've been sexually frustrated, but still want to cherish my first time. Now a days, I masturbate Fridays and Saturdays for a release, however I get the urge through out the week since I'm 15 years old and many girls(especially the cute ones) are too out of my league, but are very arousing, even though they don't notice it, my eyes wander primarily to their breasts(if they're wearing a shirt that reveals their cleavage or "side-boob" and I have a intuition of grabbing them, but I don't because I can get in serious trouble(i.e jail) for it. But If fortune favors me and I'm in a situation where I can have sex, though I'm unfamiliar(if in the future I do get a girlfriend and she's a virgin than we can lose our virginity together, If she's not a virgin she can teach me) I desire to have an impressive *** shot/ejaculation. Since life is unpredictable, I try to be ready for everything, that's why I only masturbate on Fridays and Saturdays, but when I get the urge to masturbate, it'll be so powerful that I'll give in to temptation. And If I do decide to wait for sex, should I wait for my future lover(whom I'm starting to think doesn't exist, or just go with the scene when It happens. I want to have a powerful orgasm and ejaculation since they go hand in hand for me, but I also have a great desire to masturbate that appears whenever I have free time, what to I do, hold until my chance at sex, or dive into pleasure myself? I know I didn't make too much sense in this, but hopefully you understand and can give me a helpful answer
