I know this is kinda going sound stupid, but there is a reason why STD don't stop in one generation. Have fun ,but becareful dude, she could been around the block for years. But swing away, son. If she is hot i would hit it too. Also whatever you do , always use a condom, atleast you won't knock her up , somewhat....
Plus it's your mom, if she isn't caring about yoou, your posting about how no one gives a shit about you.... Be happy someone out there loves you enough to care about you, some people don't even get that much.
