Never insert any product to the point that it cannot be easily controlled and removed. If you lose a toy in your vagina most often you can just straddle a toilet and relax your muscles ~ coughing or sneezing will help expel a toy from the vagina. If you lose a toy in the anus you MUST visit the ER for removal.
Always clean sex toys before and after use, never sharing toys if not cleaned before hand and never putting anything into the vagina after it's been in the anus (unless you use a condom and remove the condom before inserting into the vagina). Easy tip: Keep vaginal toys and anal toys separate and use only in those areas.
Make sure you don't use a silicone lube with a silicone toy. It will melt and fuse together! If pain or discomfort occurs during toys use, stop immediately. Do not use toys on broken or irritated skin. Do not store your vibrator with the batteries in it. The batteries may corrode and damage your toy.
Never use your electric or battery-powered vibrator in water unless it was specified "waterproof." Water may damage the motor or result in electric shock!
Achieving orgasm is perfectly safe and recommended for pregnant women. However, it is recommended by most doctors that you do not insert anything into the vagina other than a penis. This means no insertable toys while pregnant, you do not want to introduce any bacteria into a pregnant woman's vagina. Clitoral stimulation is recommended. Check out my article on Pregnancy and Sex under the "Articles" link. Orgasms prove to be calming for both mother and baby and can actually rock the fetus to sleep! If you are high risk pregnancy orgasm in general could be dangerous, so please get the advice from your doctor! Don't be shy, your doctor is there to help!
