Can i a get a woman pregnant if i touch sperm that was in my shirt with my finger and then putting that same finger into her virgina.

Yes: Yes, it is possible to get pregnant if sperm is introduced into the vagina on either a penis or a finger. It is not as likely to cause pregnancy as ejaculating in the vagina, but it is still possible. If you are looking to avoid pregnancy, it is best to use condoms and for the woman to use a birth control method like an IUD or implant, or pills.
