I’ve found that 2 tablets of Benadryl is enough to stave off orgasm for me. Any more and I can’t reach orgasm! I figured this out a few allergy seasons ago, and have done it intentionally only a few times. I can’t say it made my orgasms any more epic, just that it prolonged the entire experience, which usually results in better orgasms anyways. YMMV.
I wouldn’t get used to using this as a crutch, nor would I recommend taking 4-8 tablets at once, especially in combination with other medications, but that’s just me. If you do take that much be sure to drink enough water to match. From what I gather, ~200-300mg and beyond is getting into intentional drug-induced trip territory, so don’t surprise yourself!
