Twice by a wasp, once by a bee. I'm 75. My first wasp sting was when i was ten,i t got stuck in my hair, can't remember when the other one happened. I was 51 when stung by a bee, it flew up my trousers in Kew Gardens. I frantically looked for a tree to hide behind to take down my trousers. I did that and the bee flew away, hadn't left its sting. I pulled my trousers up, turned around and realised I had an audience :-).
I am regularly and repeatedly bitten by other insects, they love me.
