I've bottomed a couple of times with the same guy, we're fuck buddies. When its my turn to bottom I'm prepared. I'm as clean as clean can be but when he starts fingering me and getting ready to finger me, I clinch up. Not a lot to the point I'm shut closed but I clinch. In some of the porn I see the guys don't do that at all. It seems so easy for them to take a dick and have someone finger them. How do I not clinch up? Anyone else have this issue?
