At first i've got a lump on penile shaft, immediately after masturbation.it was bit awkward feeling that day. lump was bit painful after one day some fliud came out of it and it suppressed. the same-day i found one more above groin area which is almost similar to pus head pimple. it was painful too. Third day (masturbated again:() Between thighs and crotch there was one more similar to more pus head like pimple(4mm dia) itching a lot. so i decided to break it while bathing by having a thought that it will sub-seed again as first one. after tat no pus,no pimple i cleaned it with cotton cloth to make it dry. Forth day there was one SMALL LUMP below scrotum(sack) and above groin area (again same place). Fifth day as i cracked the pus head before, it all sub-seeded, BUT i have noticed red blister(filled with pus and blood) started coming over the same LUMP on the scrotum. its growing huge (1cm). Sixth day i cleaned it while bathing and made it dry. Seventh day blister is gone which was very painful but LUMP(1cm Dia, No Pain now) is still there, lump u cant see its under scrotum skin and not attached to testis. i'm worried and scared a lot, leading a stressful life. bit shy too to show my private part to doctors. please help me out friends.
