Can I masturbate by seeing a non nude images like fully dressed women?

Absolutely. I do it all the time. Especially with curvy women.

You can masturbate to anything that turns you on. The nice thing is that (unless someone else is masturbating you) it's a mostly private affair that happens inside your head.

We are visual animals (especially males), so images and sights of ... well, almost anything can trigger sexual excitement. Lots of boys begin masturbating using ads in magazines, or catalogs containing images of women in underwear. Each person is different, of course, and a lot depends on what appealed to you growing up. Our brains call on many things to bring us to orgasm -- physical stimulation, memories of events, sights, smells and sounds, and of course, fantasies. The brain takes all these things and mixes them together to tell the body what to do, starting with narrowing the gates that let blood flow through the penis to start your erection, all the way through your ejaculation. If you think about it, I'll bet you have a "favorite hits list" of images and thoughts that pretty much can always bring you off. You'll keep adding to those as you go. It's kind of amazing, really. So yeah, if the sight of a woman fully dressed can turn you on, go for it! Enjoy!
