I need some sources for a research paper about if our current society has become over-sexualized. I felt like it would be good to have some history involved because the standards of what is sexual has changed over the years.

TheLordHighExecu has linked you to an excellent post to which I have little further I would contribute. I would only add that Mason's The Making of Victorian Sexual Attitudes (1995) and Steven Marcus, The Other Victorians: a study of sexuality and pornography in mid-nineteenth-century England (2008) are well worth reading.
In terms of sources, throughout the Victorian period there was a steady stream of cheap, usually pretty poorly produced, erotica and other pornographic material some of which is freely available on the internet. In terms of the literature (I'll let you find your own Victorian porn), you might want to see:
Anon., The Autobiography of a Flea (1887).
If you care to look for it, there are some crude images from the 1901 edition which are available online (I've used them in teaching my courses on modern Britain because they are hilarious -- what can I say, I'm a child at heart) which depict priests with huge 'instuments' having their way with young women.
Note that wikisource has a small but eye-watering catalogue of similar texts.

The question is a little vague, but I think I know what you're getting at--expressions of sexuality, and what different cultures/societies think about it changed often.
Victoria, for instance, was quite reactionary against the excesses of her Georgian predecessors (and not without reason...King George the III had 50-ish grandchildren...none of them legitimate).
I also urge you to be careful in lumping "the Victorians" all together. Propriety and prejudices are the province of those with money, means, and religion. You're going to get a much more interesting paper if you pay attention to how class, race, sexuality, and science all informed the discussion of "sexy".
There were people calling for the gay/free love rights at this time (Hirschfeld, Symonds, Edward Carpenter, Victoria Woodhull, etc.). There were people who were totally anti-sex (Kellogg/boy scout manuals/other masturbation panic trends). There were people who did one thing and said another. About 20% of the population was infected with venereal diseases during the 1800s, which definitely added a danger to sex that we don't have (as much) today.
Obviously, there are a lot of different, interesting angles to this kind of question! Resist going the route of "Victorians prudish, we are super sexy". It simply doesn't pan out, and obscures a lot of fascinating ways to understand the sexuality of times past.
