<human>: Can you succinctly summarize the text in 1-3 sentences?

So, I'm not very hairy from the waist up. But my very lower back, ass, and upper thighs are really, really hairy. I'm 19, but this is a relatively recent development as I hit different parts of puberty at weird times. Normally, I wouldn't really care too much about this but there are now two concerns: I'm an a relationship for the first time in years, and as things get more physical I'm concerned that the body hair is pretty disgusting. Secondly, this is actually a kind of health issue, especially on my thighs. I tend to get a lot of ingrown hairs/acne, definitely in part due to the fact that I'm so hairy. 

I have never shaved my ass/thighs, and I don't really have a male friend whom I could consult for advice on this subject. I could just start shaving away, but I'm worried about it simply growing back rapidly, or making things worse with more cuts, ingrown hairs, etc. Any suggestions appreciated.
<bot>: Extremely hairy ass and upper thighs both disgusting/causing skin problems, how do I shave it and can I prevent/slow regrowth?
