Asking too many detailed questions

I have this huge OCD problem in that I need too many details about a certain topic when talking with people. I feel if I don't get my questions answered then I will wonder about it for 10 years..... This is because I have whats called "superstitious OCD". I have a problem with the number 10. If someone says 10 they have to repeat the number again for me....in order for whatever it is Im wanting to know about doesn't bother me for 10 years. If the number gets repeated I feel like the number has become 20 not 10. Just to clarify Im not delusional and I know in reality having the number repeated does NOT make it 20 but in my OCD superstition 10=10=20. This is not a problem for friends and family but for people I don't know too well people get super annoyed at me. people have even said damn u ask alot of questions and have even told me im so annoying ....Also if I don't know someone that well of course its very uncomfortable and embarrassing to ask someone to repeat it....so for the times I can get the number repeated these detailed questions that I may not get an answer to wont bother me so much if i don't get an answer...but for the times the number doesn't get repeated I have to break down and ask all these detailed questions that people find most annoying and intrusive. I understand people being upset with me I would think its annoying and intrusive too ....the problem Im having is I have become friends again with someone recently and this person is very easily annoyed and he got mad about me something stupid so we havent been talking so much the past 2 weeks. Last week I was remembering he had these family guy cups when I was at his house a few weeks ago and Im wondering some questions about it..such as how much did he pay for them and what year he bought the cups..i also want to know was he living at the place he is now or he was living somewhere else when he bought them...since we havent talked much recently that will look weird just to randomly ask that...i tried messaging him since to break the ice but he was unfriendly and didnt carry the conversation....every day I think about this and its torture on my mind....does anyone have anything similar to this? I have been on other OCD forums online and people have said yeah I ask too many questions but nobody says the degree it bothers them. So I guess my question is does anybody have to ask questions and if they don't get an answer does it cause anyone the degree of stress it causes me? Not only that but does anyone feel if they don't get their questions answered it will bother them for a certain length of time? 5 years, 10 years etc? I feel like I am the only person on the face of the earth that has this exact problem...I feel so alone...
