Definitely worth it, but if you haven't tried glass before I would just get one. Read some reviews and pick which you think appeals to you most. I honestly have always preferred softer toys, but have recently come to love glass. They just have to be the right glass toy for me and I am learning what I do and do not like in glass designs.
I noticed that the glass toys are the edne friends pick right now, and i'm wondering are they worth it even being so cheap. I have never used glass toys before and am really curious.
Well it completely depends on your personal preferences and the toy. Texture, no texture, swirls or bumps, bulb or no bulbs, etc. Starting out with something less... busy is the best way to find out. One of my first glass pieces was the rotator and the rabbit icicles. Didn't care much for the icicle, but still love that rotator!
Glass became my favorite material with the first dildo I got! Try it, but start with something simple first, bumps and some other textures are intense with the firm material. If you are interested there are three perfectly good dildos on sale with the face book promo. They are less than $15. They are all beginner friendly.
You could... but it's a VERY bad idea. There could be hot spots on the toy and there are high risks of burning yourself.
Soak in warm water for 10-15 min, please.
Yes, warm or cool water, never hot or freezing. Shocking glass can cause it to crack and even shatter. It's like pulling a glass cup out of the fridge and trying to make a hot cup of tea in it. Not a good thing.
