Tell friends about sexual experiences?

[Senpaija]

So, first of all, it is abnormal for me to share risky personal information. I used to share all sorts of things with everybody, but I have become closed over the last 4 years. Today I only share stuff if I got a good reason or simply is forced, because the alternaltive is worse.

Since november last year, I have become more sexually active, which has brought both good and bad with it. I don't normally talk about it, because there hasn't been a need, but recently this intense feeling has been "haunting" me.
I believe that I actually want to bring up my sex life to my friends, I just don't got a good reason and because of that, I don't want to tell them, but then again I want to. Very confusing...

Since yesterday my anxiety level has also been rising, which only makes it the more difficult, and at some point I probably have to tell my friends about it, if the anxiety and intense bad feelings don't go away.
The fact that I want to tell it is probably what creates anxiety, so isn't it logical that I have to actually tell them, if i want the anxiety gone?
It causes a lot of stress on my heart to.

But my main question is: Should I tell my friends about my sexual experiences, even though it is completely unnecessary for them to know about?
