Long time reader, first time posting. I'm an 18 year old girl and I personally find body hair on a woman disgusting and I have been shaving for the longest time, even when I'm not hooking up with anyone.
I understand your concern for razor bumps. If you continue shaving everything, I suggest putting on First-Aid ointment (like Neosporin) after and once a day in between shaving. This will make your skin a lot smoother and reduce the look of bumps.
Or, if you decide you want to trim instead so you don't get bumps at all, I suggest letting it grow a little bit and use scissors to trim. Then, use this. It's $9 and a great investment. You can do your bikini line and some fun design like a landing strip. It's great because you don't get irritated and you can use it all over your body; I use it on my arms and eyebrows. Hope that helps!
