Would you say I need to see a therapist?

Let me establish some premises. I'm extremely attractive, a model in fact and 18 years old. I have no problem getting attractive girls in school, or anywhere else. I have had a completely standard upbringing; two caring parents and no history of abuse. I mess around with girls from school, and my large sexual appetite doesn't impede my education or hobbies. The problem is, I'm extremely horny all the time which should be normal for my age, but it's getting to a point where I think something may be wrong. For example, for my 17th birthday party I mixed about a quarter cup of sem en into mashed potatoes and served it to the girls who I invited. Even when going to the movie theaters with girls, I do things like cu m in their soda after offering to get the food. I even did this once to my distant, extremely attractive cousin. I've been doing this for a while. Even in grade 9, I would steal mouthpieces from the attractive girls from music class, and c um in them before putting it back. It just gives me satisfaction knowing many, many unsuspecting girls have guzzled it down and have no idea they swallowed my spe rm. Many people see me as classy, attractive and intelligent, but have no idea what I do behind closed doors. Is this an issue worth seeing a therapist for? And please, if you're a prepubescent teen who has nothing better to do than spew judgmental hoopla at me, don't bother answering.
