Is there really an increase in human sexual desire during Spring???

Abstract: So... I heard of a really interesting phenomenon yesterday. I was told that during the spring time humans have a greater desire to engage in sexual activities (had to make it sound nice :-D ). I am not sure if this is true but it's the explanation a friend of mine gave for the obvious increase in physical attraction to and desire for the opposite sex that we have observed.

Hypothesis: Humans are hornier (is that a proper english word?) during Spring.

Observations:

1. Either I have suddenly become way more attractive which I doubt because for the past two weeks my hair has not been looking so nice... in fact it looks horrible, or these guys are just so horny that they cant keep away. Note: I am not talking about one or two guys. Today four different guys were doing some serious flirting avec moi in less that 30 mins! Usually one evry hour is normal... four in 30 mins was a record given my bad hair and all.
2. I have seen a significant increase in PDA.
3. There have been an increase in the amount of skin on display by females. (could be a result of the warmer temperatures or a way of attract the opposite sex???)

Discussion:

The behavior of the subjects may be due to that fact that warmer temperatures allow women to wear less clothes and show more skin therefore unknowingly appearing sexier which is driving the men crazy. In which case it may be safe to assume that in the Summer there will a greater increase in this particular behavior. It is also possible that this increase in sexual desire is analogous to the behavior in plant who will be having sex a lot as well during this period.

Conclusion:

You tell me what you think!!!

this has got to be the worst scientific report ever written!!!
