I prefer OWO, but after a whole year of mouth & gum infections (nothing to do with oral sex!) I've been left with weak, vulnerable gums and given the advice to NOT do OWO. I just can't risk it, I was off ALL work (prossie AND civvy) last year for more than 6 months in total, the pain was horrendous, the dental work even worse
And however small the risk of catching Hep or HIV through oral, it's just not worth it for me and my poor gums.
Mind you, when you meet a prolific pre-cum dribbler, or the ones who have blood in their spunk, then you're very thankful for the condoms!
If you don't like the taste, try a non-latex one.
