I hump my pillow with my penis down and place two pillows underneath my stomach and penis! i now notice a bulge on the left side of my groin area?

Here are some...: Hi! RafaelS, Your acts with two pillows very unlikely have a direct connection with a bulge in left groin. If not having systemic symptoms like fever & general tiredness, it is reasonable to just watch & wait to see if this bulge may change in its size or produce pain. Also, take a look at whole external genitalia (sac and penis) so to assure no any local lesion/ erosion. If worse In 3-5 days, see
