I'm a teenage guy who has only used a trimmer. Honestly, I've nicked myself a few times but have been to scared to use a razor. I feel like it will feel good, make my dick look bigger, and have more girls be looking forward to sucking me off but i think i'll cut myself like crazy. This sounds gay af but I also like to trim my asshole because shit gets stuck on the hairs and it makes ur butt stink so I'm also afraid of nicking my asshole. Any advice?
