Me and my boyfriend are looking to have sex for my first time in a month or so, when I am ready. But I do not want to take birth control or any other methods because they are just too too invasive and all other reasons we know etc. so if me and my boyfriend just used condoms would that keep us safe to avoid some unwanted pregnancy as im 18 and that’s the last last thing I want?

And if so are thin condoms(particularly ones from skyns just as protective as other condoms that may be marked something like or similar to ‘extra safe’)?
