Scared To Orgasm?

Anyone else ever scared to orgasm? I always get so close to having an orgasm, but then I stop myself from having one. I’m not sure if this is out of fear of what it feels like? Although I’m sure it feels amazing! There’s just something holding back from going all the way. Could it be that I’m still a virgin? Whatever it is, I hope I’m not alone, I’d like to know why/if any of you have the same struggle. Please share!
