I would NOT reccommend trying, doing any of these methods you should be very experienced in doing so, doing either of these choices wrong can hurt your snake. I would have someone experienced do it for you, and watch closely and pay attention and let them explain how to do it to you and show you. Watching in real life is easier than videos, also because you have someone there to explain to you. Just don't attemp it right know, I myself have had my bp for over a year and still dont have it sexed because I am not experienced in doing so at all and I can't find anyone that knows what they are doing.
Hope I helped.
