As people become more accepting and open-minded about sexual matters, many men are becoming more interested in different forms of sexual activities, some of which involve other men (even though the participants may identify as totally straight). For example, some men enjoy engaging in a practice known as docking, in which the glans of one man’s penis touches the glans of another; the foreskin of one penis is then stretched over both penises as far as it will reach, so that the "owner" of the foreskin has his penis totally covered and the upper portion of the second man’s penis is snugly fit inside. While some men find this an enjoyable practice, there may be some penis health issues that they need to consider.

It’s not really clear how common docking is. Since it involves at least one participant possessing a foreskin, and since the circumcision rate in the United States is so high, it is likely less common in America than in some other parts of the world. However, for those who do enjoy docking, the following are a few penis health issues that they might encounter:

- "Stuck" foreskin. This does not happen very often, but it is possible for the partner’s penis to become stuck inside the other man’s foreskin. This usually happens when the partner’s penis is not fully erect when the foreskin is first engaged; if the glans expands significantly after covering, it may become very tight, making removal of the penis from the foreskin difficult or painful.

- Foreskin damage. Sometimes stretching the foreskin so much may result in small tears in the foreskin. This is more likely in instances when the foreskin is stretched very tightly. Being sure that both penises are very well lubricated can cut down on the chances of tearing.

- Sexually-transmitted infections (STIs). Almost any kind of unprotected sexual activity can run the risk of a sexually-transmitted infection if one or both of the partners is already infected (and it is important to remember that not everyone is aware that they have contracted an STI). The release of semen or of self-lubricating pre-seminal fluid, can carry the seeds of infection, so when two penises rub together in this way, the route of infection is clear. Sexually active men should be tested every three months for possible STIs, as one way of helping to prevent transmission to partners. And if they know they are infected, they should refrain from activities (including docking) which might result in passing on of the infection.

- Yeast infections. Though not as serious as STIs, yeast infections can be annoying and uncomfortable. As with STIs, men who are aware that they are currently carrying a yeast infection should refrain from docking.

- Rashes. Sometimes a penis rash from one partner can be passed on to another from docking. In addition, it’s possible that some inactive allergen on the skin of one man, which does not produce a rash on his penis, may be passed on to another man who is sensitive to it and may therefore develop a rash.

- Crabs and scabies. These common parasitic creatures can cause significant itching and embarrassment. Do not dock with a man with these or similar conditions.

- Soreness. Finally, simply having one’s foreskin stretched top such an extent may result in lingering pain for several days afterward.

Taking steps to prevent or treat penis health issues due to docking makes the experience more enjoyable, so definitely start by regularly applying a top drawer penis health oil (health professionals recommend Man 1 Man Oil, which is clinically proven mild and safe for skin ). If soreness from overstretching is present, soothing the worn skin with an oil that contains both a high end emollient (such as shea butter) and a natural hydrator (such as vitamin E) is urged. The best oil will also include vitamin D, the so-called "miracle vitamin," which has proven benefits in fighting diseases and supporting healthy cellular function.
