What to use to shave pubic hair?

Ok so I am 17 and a super late bloomer. I have had pubic hair for a while but compared to all my friends who shave often I am completely clueless. I have yet to shave my pubic hair. I do shave my mustache about once a month. I’m just wondering if I can use my electrical razor on my pubes. I would ask my dad for a razor for it separately but I’m not that open with him and don’t feel comfortable. I just want to know if the razor I use would work and not hurt or anything, the model is Phillips Norelco Oneblade

Thanks.
