Glass- Hot or Cold?
Do you prefer to use your glass toy heated from warm water, or cold from the freezer?

To me, the glass is completely smooth and almost always a little cool at first and is very hard and unforgiving. Silicone is usually warmer, and softer.

For me the big difference is drag- silicone has it, glass does not. Lube makes it less distinct, but it is still noticable.

Also silicone has some give while glass is completely hard.
