Generally no problems with Levitra, but that is a better question for your MD. There are also herbal products, such as Prolong, that claim to let you last longer. I'd beware of herbal products as the manufacturers/sellers generally will make false claims just to get you to buy the product. For some individuals, they do tend to work. Whether their physiology is more receptive to these herbal suppliments or the placebo effect is the real reason, I don't know. Some people will have their MD give them a Rx for an anti-anxiety medication if the problem is anxiety related. The benzocaine ointments can be marketed as being specifically for premature ejaculation, but it's going to be the same as anbesol, orajel, numzidt, Americaine Topical Anesthetic First Aid Ointment, all marketed for relief of dental pain. The peak local anesthetic effect is within 5 minutes or less. The duration of action ranges from 15 to 45 minutes.
The downside of using benzocaine is that if you use it and go right for intercourse, you're going to get her numb as well. Plus, you'll be numbing your penis that will decrease your pleasure - until the numbness wears off.
