I immediately lose interest in guys I found attractive when they start flirting with me, why?

Whenever a guy I try is attractive starts flirting with me I lose interest completely it js grosses me out.

I find it most attractive when a guy and I are just joking around if that leads to flirty territory usually that’s fine but then I’ll start feeling ill

problem is this wards off most men because I feel ill and block them without explanation.

I have good self esteem and I want a boyfriend how can I stop being grossed out when guys flirt with me?
