Seems to be a penis-pump party or something...

Penis pump

A penis pump is a cylinder that is fitted over the penis, with a manual or motorized pump to create suction. The apparatus creates a partial vacuum around the penis, engorging it as blood is drawn in. As vacuum increases, the difference between the inner blood pressure and the pump pressure increases as well; excessive vacuum causes vascular damage.

Penis pumps can be used to temporarily overcome symptoms of impotence, but do not cure the condition: a ring must be applied to maintain the erection which will otherwise immediately subside. Pumps may work even if there is nerve or vascular damage preventing a natural erection.

A flexible compression ring (or sometimes more than one), commonly called cock rings when used recreationally, must be used. It is fitted on the open end of the cylinder, then an erection is created by pumping. Then the ring is pushed by hand onto the base of the erect penis before releasing the vacuum. This restricts blood flow out of the now erect penis, enabling the erection to be held even in the presence of problems of the vascular or nervous system which would otherwise lead to immediate loss of erection. In the best circumstances erections can be maintained for a considerable time, but manufacturers' literature recommends that, for safety, rings should be removed after no more than 30 minutes. Very prolonged use (hours) will cause permanent harm.

A personal lubricant of a type not harmful to the ring material is used, primarily to make a good seal at the base of the pump to prevent air leakage, in the same way that vacuum grease is used with a laboratory vacuum pump. It also makes it easier to slide the ring off the cylinder, and later to remove the ring.

Pumping must be done very carefully to avoid serious injury: over-enthusiastic pumping can burst blood vessels and form blisters. In some cases the testicles can be unexpectedly pulled into the cylinder, causing discomfort, pain, and possibly injury.[citation needed] It is also believed that the rim of the cylinder can cut into the skin and over time cause damage to the ligaments surrounding the penis. Impatiently pumping without reading explanatory material can produce too much suction (any pressure lower than 10 torr/1,333 Pa)[citation needed] and cause permanent and irreparable injury. Attempts at using vacuum cleaner units for this purpose have resulted in extremely severe injuries because the suction is far too powerful.

Pumps used with rings are virtually always effective, as they operate by a simple mechanical process, in cases of ED, even when pharmaceutical methods fail. They may nonetheless be found unsatisfactory due to the inconvenience and similar factors.

The effectiveness of penis pumps for permanent penis enlargement was examined by Kazem, Hosseini and Alizadeh. They studied 37 men with penis length less than 10 cm and found no significant change in penile length after using pumps for six months, although the follow-up have found 30% satisfaction with the method. The conclusion of the paper stated that vacuum treatment of the penis is not an effective method for penile elongation, but provides psychological satisfaction for some men.

Nope... I'd pay a Dominatrix to snuff me in the worst way first!

I would also assume a gay one at that.

Find out from your doctor which penis pump is right for you. Umm...who suggested a group photo?

This is one of those instances where I am at a total loss for words.
