i cm using my right hand and wipe it with towel using my left hand.. i do not know if my left hand touches the semen.. i fingered my girl friend using my left hand but before i fingered her i fixed my self and we kissed... there is an interval before i fingered her so do you think there is still alive sperm?? i do not know if i have wet left hand.. maybe moist or something but i am quite worried... her period is ireg but usually 28 days but last month it is 33.. will it go back to 28 days?? will it still be 33?? is she pregnant?
