I thought about waxing my ass. I guess I'm not anymore

Actually I tried it at home myself so it ended up like that
Beauty salon is better cause they are professional
And just don't try with your vagina bc I don't think it's worth such pain

What if I...lack...said genitalia.

idk...
just keep thinking how nice it'd be when it's all smooth that would kinda keep you going

Pain is temporary

You tell that to my vag

SHAVING PEOPLE WTF IT TAKES LONGER YES BUT IT'S MUCH MORE PLEASANT

Waxing is beautiful. Pain is really nice if you can take it. But like otamega said, it is temporary. Doing it on the legs isn't as bad as doing it elsewhere softer. Waxing the private area feels soo good. If it hurts too much (or anywhere on the body) just put pressure on it for a few seconds/minutes.
Shaving is good but for some, hair grows back like the next day. My problem is my skin is very sensitive so when I shave, it causes irritation, no matter how softly I do it or what I use for before and after so I always wax. NEVER shave your arms or on the body or face! U'll have beard like hairs. Legs, underarm, etc is fine for shaving. If you keep waxing, the hairs start to thin and the pain will be a lot less. Put cream/oil on the places you waxed to soothe it and get rid of the redness. You can use hair removal creams which is absolutely pain free. It lasts 1-2 weeks. Or you can epilate. This also hurts but you can place ice cold cloth/bag on the skin for few minutes. Pain is less.

Here is another thing about me
My hair is awesome but except for my head it a always awesome in the place it shouldn't be
So it grows back like super quickly
Hair removal cream? That last for about 3 days for me
I tried wax my legs a week ago and now the hair is already like almost 2mm

Same. My hair used to grow back quick. Being half middle eastern u can imagine the struggle. If u wax properly it should last longer than 3 days. Leave it long time & smooth down always & rip it swiftly. Keep doing it till u get better results. Get a female family member/friend or go to the salon. U can use the strips or u can make the wax urself with heated sugar-like in a pan and use cloth strips to remove off the skin. Pain is greater tho. Like I said you could try epilating. (For the face u could use the string method we like to use)
If none of these work, or you don't like using them, there is a machine that uses radiation to remove hairs. This thins the hair and if you use it constantly, there will be less and less hairs present. Its not very expensive (in the UK its slightly over £100 depending on what type u get), you can use it anywhere, is safe and is simple to use so check it out. Otherwise there's nothing else you can do about body hair. Ask around from professionals.
