According to this article and recent study:
"It's confirmed: Online dating is the way to go if you're looking to get lucky. According to a recent survey published by the Sexuality Research and Social Policy research journal, one-third of women who meet people online have sex on the first date, and a whopping three-quarters of those surveyed do not use a condom. Meanwhile, a mere 27-percent engage in oral sex on the first day."
Researchers attribute the sex-on-first-date to be caused by the sense of familiarity people gain by having several casual or lengthy conversations online prior to meeting. This sense also causes people to feel more trustworthy or knowing of their partner which makes them less likely to use a condom.
Uh...hello, straight women? Despite how crude this may sound: You can get rid of that unwanted pregnancy. You can never get rid of those unwanted herpes. Wrap it up!
