I am 18 year Male teenager. And I am having a girlfriend of same age. And her boobs are small she wears a bra of 30. So please suggest something to increase her boobs and form proper shape. And also she is afraid of sex because of pregnancy and Aids. Would it be safe for us to have sex? And when she gives me blowjob she drinks my sperm so is it harmful? Please give answer for this 3 questions as we are very worried.
