A new study has found that teenagers are surfing the web to answer questions that many parents may be uncomfortable bringing up — whether one can get a disease from oral sex, why changes are happening in the body, how much alcohol is safe to drink, for example — but perhaps not as much as you might think.

The fact of the matter is, teenagers want to know the answer to these questions, and if they don’t get them from their parents, they’ll look online, according to a CNN report. But the study had some surprising results as well when it came to how much they learned from their parents.

The study, conducted by researchers at Northwestern University, finds that — not surprisingly — young people think a lot about their bodies and about some very grown-up things, ranging from puberty to drugs and alcohol to hygiene, all while dealing with the stresses of school and life.

Parents are still the most popular source for advice for teenagers, with 55 percent of American teens saying they get “a lot” of their information on health from mom and dad, followed by classes at school at 32 percent and then medical providers at 29 percent, with the Internet coming in fourth at 25 percent.

And even though you’d expect that teenagers would flock to the Internet for answers to questions that can be uncomfortable to talk about with parents, the survey found that just 13 percent of teens resorted to that. Instead, they used info from the Internet for supplementary research, or even to find information to help their parents with medical questions.

The study found that teens most often went online to learn how to stay in better health, especially when it comes to exercise, nutrition, and sexually transmitted diseases or emotional struggles.
