So me and this guy have been talking for awhile and him and I both agreed to have a casual sexual relationship with no strings attached. We've both talked and discussed our limits and kinks and about how im not on birth control. And I was wondering if I should ask him if he's been tested for STDs? He's had multiple sexual partners and is known for sleeping around. I've never asked a guy this question before and I just don't know how to ask it does anyone have any tips?
