Some of you already know how many times i posted this issue, but it seems like the culprit is having a 3BBB-3BA body/preset. For some reason, while flacid, the penis clips through the balls, but while erect it functions properly. Trying to get potential fixes i browsed this forum a lot, and unfortuntaley i did not find any solution but instead found a lot of users having the exact same problem.   If anyone knows how to fix this it will be very appreciated.
