We can view your questions. They are pretty graphic for 13 year olds, they don't need they details of your private acts. Neither do the rest of us. If your question is restricted to, "can I be pregnant by having unprotected sex?" I will just tell you now, the answer is, yes, yes, you certainly can. A sheet is not protection. It sounds like you need to drag your partner to Planned Parenthood with you before you start an unplanned family.
not alot of people wanna hear the personal details of another persons intimacy with someone else in some way some people can go way far on details some people don't but knowing this site is open to the public and age groups of all sorts we half to be considerate of others older and younger then us and yeah hun
