I'm 23 years old, and I masturbate a lot. Due to being overweight I can't insert my fingers into myself, so mostly I rub my clitoris. I haven't been able to achieve orgasm. Is there anything you can tell me that might help. Thanks.

Fortunately you are old enough to purchase sex toys. Those might facilitate masturbation and orgasm for you. Quality is important. It's a good idea to purchase something you can sterilize in boiling water. Silicone is durable, yet soft enough for this. Jelly rubber is another common material, but it doesn't sanitize quite as well. Just make sure you use lubricants that are compatible with either material. Water-based lubricant (Astroglide, KY Liquid, etc.) is safest. Some toys are just vibratoers and should not be used for insertion. Some toys are dildoes that can be inserted, but don't do much else. And then there are vibrating dildoes which are good for both and/or either. Your purchasing options are in-store, mail order or Internet order. There are a lot of great, sex-positive, woman-friendly sex toy vendors online. You can Google for them. The great thing about buying online is that the really savvy retailers know to be discreet. So they'll use an alias on your credit card bill and on the parcel. If you don't know what to buy, you can search for online product reviews, too.
