mornin Bugaboo, Rubbing and touching is a great beginning for you, it takes some time and practice for you to know what feels the best for you. There are a few different ways for self stimulation and they are all safe. Try the water trick. If you have a hand held shower, position the spray directly on your clitoris, use warm water. You can either lay in the tub or stand up, what ever is most comfortable. If you don't have a hand held, try using the faucet. With warm water coming from the faucet, lay in the tub and position your self (vaginal region) as close to the faucet area as possible. Get your legs up on the wall and let the water flow onto your clit. In the meantime your hands are free to touch your breasts and nipples.
Buy your self a battery operate toothbrush, use it on the non bristeled side (obviously) Purchase a vibrator. You can find a store at the mall that carries them, like Spencers if you have that store there.
You can break your hymen many different ways, i.e. riding a bike, a horse, gymnastics, trauma or accident. Introducing a vibrator can break it also, but you will still be considered a virgin.
People CAN NOT tell if you masterbate unless you wear a sign around your neck that says you do, or unless you tell them yourself, which is your business only. The only way your parents will know is if you tell them, but they don't need to know. What you do in the privacy of your bedroom is also your business, within reason. Providing your not doing something illegal or elicit in there.:-)
