Ay anak, this is a question best discussed with a doctor or visit a family planning clinic para sure, they can explain the risks properly at walang judgment, promise! But between us, a few of my mum friends have asked the same thing, at ang common concern ay pre-ejaculate (kahit walang husto) may sperm na. Kaya yung butas sa condom, may risk talaga, pero it depends on many factors na talaga lang better explained ng medical professional. If you're worried, don't wait, go to a clinic malapit sa inyo ngayon pa lang, okay? They're there to help, hindi magscscold. Take care of yourself!
