I have seen males hump until they knot up like that. It is important that you put his penis back in place. Most likely the sheath has some hairs on the end that have rolled the skin under that is on the end of the sheath thus preventing the penis to be completely covered. You can gently unfold the skin that is at the end of the sheath until the penis is covered. If the penis is exposed for a long period of time it can swell and get very painful. |
