Safety as in become sterile or else? If the former I don't mind, I don't want kids or my own so I would be completely find with it.
I currently shave; waxing? I used to wax for sport reasons and I have a high pain threshold but isn't painful down there? Do you know of any place in London who does it that you could recommend?
I'm not too sure why it's not safe but I was told that it's not by the person that waxes me. I would imagine it's due to sterile reasons. Not wanting kids is beside the point, I think.
Waxing hurts a little but after time the hair stops growing and becomes less and less, so you don't have to go so often. If you don't mind a little pain then you can try it. I have been waxing for nearly 5 years now and I wouldn't go back. It feels more hygienic and more sensitive, so it's a bonus all round.
There are many places that provide waxing for men, you just have to Google it. However, if you want me to give you a recommendation for a place then I am happy to PM you. Let me know.
