One day I masterbated and ejaculates in the bathroom but their was no sperm no sticky liquid on my hand because I only hold penis for masterbating then I came out from the bathroom and sit on bed without hand wash then after 5 minutes my sister come and hold my hand because she is naughty. Then she uses the same hand to touch her hip and lower abdomen with all clothes on ( a shoot, jeans, panty, a pad because she is on her period). So my question is that can she get pregnant by touching my hand and by touching lower abdomen by same hand with all clothes on above mentioned??? She is also on her 4th day of her period that time and her period lasts in 8 days and her menstrual cycle is of 45 days . Please help doctors?? As I am very worried???
