Good question but the answer is a bit tricky or let's say complicated. First of all, the FDA blah blah, what you read here is not medical advise and these statements have not been approved by the FDA.

Super Dragon Delay Spray
As you can read in this article having more sex can have an effect on enlarging your penis. You'd ask so what about Dragon Delay Spray? Well, Dragon or other delay sprays prolong the time of intercourse, and the longer you have sex, there will be more blood circulating around your penis and since penis has no bone, it may help with increase in the size.
Just note that, you would need to have regular sex and the duration of each session needs to be long enough to have an effect. I really suggest you read the article I shared above and do your own research and you'd have a better idea about this.
The Dragon Spray will NOT increase the size all by itself, it is the intercourse that may help gain some increase. So do not expect to spray it on your penis and magic happen.
Dooz Delay Spray as the name says is a delay spray which may help with premature ejaculation. The product contains Lidocaine which is a topical anesthetic. So, you could spray it on where you have pain and it may help with reducing the pain. You must not spray it where there is an opening such as blood coming out or if the skin is irritated. Contact a medical professional in such cases. Please note that what you read is not medical advise and these statements and products have not been evaluated by the FDA.

Reman's Dooz Delay Spray
If applied to penis, Dooz spray would remove the sensation for the bigger part of the intercourse and when sensation returns, is when most men would ejaculate. If you are like most other users, I am sure you'd not really like the fact that it numbs it down there but then, what are the alternatives, right? It at least enables you to satisfy your partner and that's what I would like to achieve.
You may ask, how much time do I need for the Dooz Delay Spray to work?
Well, that depends. Start by giving yourself at least 15 minutes and then adjust accordingly. You would need to spray about 3 times to the head of the penis before intercourse.

NO!
Pregnant women are advised to consult a doctor even when taking a headache or pain killer. Pregnant women should not take any sex enhancing products.
This is not a medical website, we are also not medical professionals, for better answers you would need to talk to a doctor but from what we have read in most of the label of sex enhancing products, toys, or even some gels, and lubes, pregnant women should always seek professional advise on such matters from doctors.
