Don't you think that masturbation as well as partner sex can become boring? Don't you think that it requires novelties, experiments and spicing up? I do think so, that is why I am always in search of new ways to masturbate and I want to share my experience with you.
First of all I want to say that I use plenty of positions for masturbation. I masturbate lying on my back, sitting in the arm-chair, standing with my legs apart, standing on my knees, etc. Each position gives me different sensations and even different orgasms. I do recommend you to experiment with positions.
As well I recommend you to try unusual for you ways to masturbate. For instance, did you ever masturbate in water? This is really amazing! You can take a bath and get dual pleasure - why to stay idle in the tube? Why not to stimulate your erogenous zones there and not to achieve great orgasm? What for me, I do the following: I turn on the water and position myself so that the water flows directly on my clitoris - this is very nice clitoral stimulation! Try it!
By the way, you as well can masturbate with sex toys in water. There are plenty of nice waterproof sex toys for your pleasure. What about playing with a vibrator in tub? I do so, and I have plenty of waterproof vibrators for this purpose!
What to sex toys, I do think that there should be plenty of them. You are very likely to get fed up with a sex toy if you use only it day by day. The more various sex toys, the better! I have plenty of various dildos and vibrators. I do love female sex toys such as clitoral vibrators and vaginal balls and I buy a new sex toy nearly every month. Masturbation cannot be boring if you are a creative person! Explore your body and have fun!
