Hi doctor. For last few days my girlfriend is urging for sex. Initially I neglected her urge but I think now the time has come to fulfil her wish in her upcoming birthday. We love each other. We have come closer many times since we are early 17 did everything except the hardcore. Should I proceed? Is there any risk (both of us don't have any transmissible disease) ?Actually I too want her physically because mentally we are United. If no risk then please provide us with suitable instructions so that she don't pursue the tendency of any kind of pregnancy and we can get the pleasure to the fullest. Nd last but not the least she had studied from a magazine that sex during periods is 100% risk free and it will help her to reduce her menstrual pain. Is it true? Thank you.(now we r of 18+)
