I ll say one thing DO NOT USE any “delay spray.” These sprays contain Lidocaine or some other numbing agent. Not only are these sprays usually ineffective, but consider what else they can do: if your penis is numb, then what do you think will happen to your wife’s vagina? It will be numb too. And if you’re both numb, you won’t feel anything (not an ideal situation, right?). These sprays may also contain substances which can burn or irritate both the penis and the vagina.
Try babyoil or for better sensation massage oil that it will be work better.
The delay spray is anesthetic agent. it numbs your nerves. If you apply more, it may affect your partner's vagina making it numb. Use spray sparingly.Sucking after spraying may not be palatable to your partner.The effect of the sprayer wears of after sometime. there is no side effect for this drug if used for some time.
