Want to bottom discreetly for 18-20 - ish

Pretty new to any of this. I'd like to bottom for just one. Maybe more regular if all goes well. Dark and discreet location here that's easy in and out. You must be completely clean or do not respond. 5'10 175lbs here. Clean w/m and take great care of myself. Up for trying oral as well and see how it goes. This is for tonight after 9pm.
