Which product does what
There is a lot of muddled marketing in this category, so here is the honest split.
Anaesthetic sprays. Lidocaine, benzocaine, or a lidocaine-prilocaine combination. These reduce sensitivity in the glans, raising the threshold at which the ejaculatory reflex fires. This is the mechanism with actual randomised controlled trial evidence behind it for lifelong premature ejaculation. It is also the mechanism that can transfer numbness to a partner if you apply it carelessly.
Botanical and performance topicals. Formulas built around plant extracts, positioned around circulation, comfort and confidence rather than around numbing. Fortify is in this group. It is a different proposition from an anaesthetic, and we are not going to pretend otherwise.

Knowing which one you are buying is most of the decision.
How to use a topical properly
- Patch test first. Inner forearm, small amount, wait a few hours. Do this once, with any new topical.
- Apply to clean, dry skin. Concentrate on the underside of the glans and the frenulum, which are the most sensitive areas.
- Wait the time on the label. Five to fifteen minutes for most anaesthetic sprays. This is not the step to skip.
- Wipe off the excess. With an anaesthetic, this is what prevents transfer to a partner. A condom adds a second layer of certainty.
- Start with less than you think. Too much numbness is its own problem — it can make it hard to finish at all, and it takes the pleasure out of the thing you are trying to make last.
Where this fits with everything else
Delay topicals are the fastest-acting tool for control, but they are a tool, not a fix. Premature ejaculation has behavioural, psychological and physiological components, and the durable improvements usually come from combining approaches — the start-stop and squeeze techniques, pelvic floor work, addressing anxiety, and a topical for the nights it matters.
The lasting longer guide lays out the full picture, including the honest note that a constriction ring is not a PE tool, whatever the internet says about it.
When to see a doctor
Premature ejaculation that is new, that started after a period of normal function, or that comes with pain or other urinary symptoms deserves medical assessment rather than a topical. Lifelong PE also has prescription options (certain SSRIs, prescription lidocaine-prilocaine sprays) that outperform anything sold over the counter.Keep reading
