Thanks for choosing health care magic for posting your query.
The kind of problem that you are describing are very common among the young age students. Having sex is one of the most primitive behaviours which even animals of lowest origin perform. You have mentioned that you have read a lot about ways of having sex and I am sure you might be knowledgeable enough by now to know how to have sex. If still not then you should meet a sexologist/psychiatrist/gynecologist who can give you information on how to have sex.
Regarding you apprehension about pregnancy
, you need to understand that condoms are the most common modes of contraception
and are quite effective as well. Although not 100% but still very effective and also help in preventing various sexually transmitted diseases.
you and your boyfriend should discuss about the sexual act and both of you should take some time and involve in non-copulatory sexual activity for some time so that your fears of having sex will be reduced.
