Why do I what? Please can you be more explicit? Do you think that stating facts, giving logical explanations and presenting the research findings is a problem somehow. I would be interested to know how... Most people just give their opinions based on emotional beliefs. I provide sex information for free for those who are interested. You are not obliged to heckle for no purpose. That is your choice. It is not my job to convince you of facts that you cannot accept. Sexual ignorance is universal - you are not alone.
Why do so many people assume that they know all there is to know about sexuality
Your previous assertion for which you offered nothing but "common sense". If common sense is an appropriate source of information - everyone is an expert and is justified in knlowing it all
No one can orgasm from stimulation they do not control. Why do we expect women to accomplish what even men cannot?
