Penile lump, help!

Hi guys, I came bck from the carribean yesterday where there are tousands of mosquitos and I have loads of bites but I suddenly noticed a smallish bump on the bottom of the shaft of my penis. It is slightly red but mainly skin coloured and gets more noticeable when my penis is erect. The last time I had sexual contact was around 2 month ago so seems quite random! Is it just a bite or sonething more serious? Thanks

Hiya to be honest it is probably a mosquito bite. But it is better to be safe then sorry so if I was you I would have a full sexual health check you should have these at least every 6 months an every time after having intercourse with a new partner. Good luck
