Iam aboy and in the age of 16 I had sex anal myself through the introduction of some sharp objects in the anus and the practice of how short I am now in. I do not 4 years ago .. But I will extend to the army after 3 years and they will inspect the anus just by looking at it .. even if they discovered I had sex anal will happen to me a problem!!!
Is it possible to discover I had sex anal by just looking ..
Will be discovered, even if what is non-medical solutions to prevent the discovery I had sex anal??
Your post is extremely difficult to read and understand but I'm assuming you're asking the question "If I insert something into my anus, will someone else know just by looking at it?". The answer is no, they will not be able to tell.
However, I caution you on using "sharp objects". You can cause serious damage. I recommend you use things that are smooth with no rough/sharp edges.
