Ice is also a brilliant thing to incorporate into fellatio. When you take a small piece in your mouth (and suck it a moment to let any sharp edges melt), and then take your lover's penis into your mouth- the sensation of hot and cold can be extremely intense.It can also provide delay, because the ice acts as a numbing agent. If your partner has issues with premature ejaculation, than Ice can be used to help. It can be very intense to have Ice in your vagina or anus while you help your partner in this way, but it's all for a better experience. Just remember, for some, Ice also acts as a refractory agent- which is a fancy way of reminding you that the human body is designed to bring the bits in during the cold, or in other words- too much Ice and equal no erection.
