Is it wrong to think of having sex with a women when masturbating if you're under 18?

Hi Someguy

Your not doing anything wrong you can think of woman or guys whatever suits you.
It is normal to have curiosities towards sex and fantasies.
So it just comes down to what's right for you and what your comfortable with.
If you feel uncomfortable with something your doing then stop.
It's normal to think about and imagine all kinds of different things about sex so just do what you feel is best for you.

Thank you so much I used to think I was really messed up for masturbating since I was li!e 10 When I started now I don't thanks

Your welcome.
Your not messed up and your doing the same things many of your friends and classmates are doing.
Masturbation curiosity and fantasies are all part of growing up and most guys experiment with it as soon as they discover how good it feels.
It's normal to be curious about girls and also wonder how you compare to other boys it's all part of puberty and discovering your sexuality.
So no need to worry sounds like your doing many of the same things are other guys do and you have discovered what feels good for you and you discovered it early.
