At least i think it'll cause many harms to ur genital system

1- Epididim enlargement & excitement

2- Some doctors beleave that it can cause varicosel

3- it will disturb ur penis sphincter by holding much larger amoiunt of blood in it

So i think i'ts better not to do it.

U can do many harmles things like using Lydocain spray or delay sprays, delay condoms or other things

For the anal thing I agree with u, It'll cause u a great orgasm & explode u like a volcano
