My whole life I've attracted these fuckers like bees round a honey pot.
I've had holidays blighted from the age of since when I can remember right up to present day (late 50s) in the UK and Europe, often needing medical assistance.
They find me, bite me, I swell up, blister, itch, go septic. What on earth can I do to prevent it? Family get the odd bite - but they literally seek me out and feast on me!
