No, it is best not to. The time needed for the healing process in the body tissues is 48 hours and this depends on the type of tissue. The muscular tissues need less time for healing than the nerve tissues. If you practice these exercises twice per day, the tissues of the penis will not have enough time to heal completely. This can be damaging if practiced improperly or too often.
A small penis isn’t more sensitive than a larger one, but surprisingly there is some correlation, many men with a relatively small penis report that they ejaculate prematurely. From the purely medical point of view, this could be conincidence, but not from the psychological. No matter how important or unimportant penis size is for the female partner, men with a smaller penis often feel unsecure, at least subconsciously. Insecurity leads to stress and bodily tension, which encourages coming too fast. This subjective failure causes even more stress the next time, a cycle that’s hard to break. That’s the main reason why penis enlargement often assists in lasting longer in bed, too.
Dermal fillers or surgery are a way to increase penis size. “I do a lot of dermal fillers simply because many men, understandably, don’t want to go under the knife. Consistent with other nonsurgical procedures which use dermal fillers, male enhancement works by way of injection. Depending on the patient’s goals, a filler is chosen and then injected into the corpus cavernosa of the penis. The filler is then worked through the penis to achieve a uniform increase in length and girth. Dermal fillers are an excellent option for male enhancement because they require no downtime and patients can return to sexual activity the same day. Filler are less of a risk than surgery and, because they are temporary, carry no long-term undesired effects," says Dr. Mirza.
