Is it normal to masturbate? For the guys & girls

Sure it's normal! And healthy too.
Humans have the need for sex, and when they don't get it from a partner, then give it to themself. No problem!

It is in no way wrong for anyone to mastrabate as long as it does not interfere with their sexual relationship that they may be in.

I do it all the time. I don't think that I can go to sleep without getting off. The only time I don't do it is if I have sex right before I go to bed. Even if I've had sex earlier in the night, I'll still do it. If I'm home alone and bored, guess what, I jack off, sometimes every hour or so just cause I can. Nothing wrong with it in my eyes, from what everyone says it's healthy. At this rate I should never get E.D. If you don't use it, you loose it!

Completely 100% normal and healthy for both guys AND girls. There's nothing 'wrong' about it, so long as it's in moderation, and doesn't affect your interpersonal relationships in a bad way (i.e., addiction, porn-creep, etc).

To be honest, when I was a teen I wasn't all that comfortable with myself, and didn't see the point until I actually learned how to do it properly - now realize that everything (and everybody involved) benefits from knowing and being comfortable with what works for you. Also makes it both psychologically and physically easier for us ladies to 'get there' quicker.

This girl's BF should be encouraging her, if anything.

Definitely enjoyable and okay. I think knowing my own body has been key to better sexual relationships.

I answered that I don't myself, but just so it's clear, I don't think it's wrong. I just...don't. Never really had the desire to. But I don't think badly of anyone who does.
