While foreplaying and evrth, i maintain a hard strong erection.more than perfect.when about to put condom for intercourse and stuff, i lose erection?!

Maintain foreplay: To maintain a firm erection, do not interrupt foreplay while putting on the condom. Your partner could put it on for you and make it part of the stimulating experience of foreplay.

Probably OK...but...: Situational anxiety and distraction plays main role in losing erection. So, think about what you can do to be in a more relaxed, anxiety-free environment. Meanwhile, slow down the frequency of trying to have erection and coitus. Remember: overindulgence and obsession generate a lot of negative impact onto personal life; practicing healthy lifestyle will benefit anyone a lot. Best wish ... Always.
