TRYING NEW THINGS IN BED

SO , me & my boyfriend have always been into "risky" sex as in almost getting caught. It's really a rush to know at any moment we'd get caught but that's about as kinky as it got. We'd always have normal sex which over time got kinda boring when the most kinky we got was actual penetration. So recently we've been trying new positions , new tricks and even period sex. Every time we have sex , something new happens whether I introduce it or he does. WELL TODAY , he was eating me out ... and his tounge went farther down that usual and well .... he ended up eating my ass . And I don't know how I feel about it . Part of me is like ... really shocked another is grossed out and another is totally cool with it . Seemed like he really been wanting to idk we haven't talked about it at all and I feel awkward . ALSO my ass kinda hurts now .
