I'v never fucked a WG bareback, but had a couple of affairs in the past where it was bareback. Yes, taking a chance even if she weren't a WG, but just cant perform with it covered. Even Viagra don't help when covered.
I'd wash my cock before and after, plus put some TCP on it after.
Must say I did worry about catching something. So lucky I got away with it. Perhaps the TCP helped?
Wonder if there is any type of barrier product other than a condom can put on cock to prevent infection??
