I need help with a fetish

So Iv always had a fantasy about having a stranger ejaculate into my panties. I know this is extremely strange and odd. Iv had this fetish for almost 10 years now and have never had the nerve to ask (I’m somewhat shy). As you can guess not just anybody would be willing to participate. The approach alone is nerve racking, much less the act itself. Any ideas of how I can cure this fetish? Thanks in advance!
