<human>: Dear Sir, I am a circumcised male in my 20s, I have refrained from sexual activity for more than 2 months and have experienced slight enlargement in the penis and the testis due to vaso-congestion. This has lead to the skin of my penis to become overstretched and during masturbation the frenulum was not torn but the part under the glans became red in general with white color in the middle and no bleeding occurred at any stage. Will the inflamed frenulum ever fully heal turning into non scar tissue and to go back to the original state? or will the scar tissue always remain? Would any of this reduce the penis size? What are signs of infection?
<bot>: Thanks for asking in Chat Doctor forum In short: Temperature around it may cause increase and decrease in size of scrotum and penis. Explanation: Usually in winter as the muscles of scrotum contracts to put your scrotum attached to the body you may feel its size has decreased and opposite happens in summer. So, don't think about this.  But, for your frenulum tear/injury don't masturbate that roughly to cause tear. Give rest to it and it will heal automatically. You can apply point tobramycin locally for time being.  Visit a doctor to examine and diagnose your problem properly.  Good luck
