Do you last as long in bed as when you masterbate?it usually takes me 3-5mins when i masterbate. sometime less than a min if i'm too aroused.is it ok

It is not unusual: for men, especially young men, to quickly come to climax when engaging with a partner. So I would say "lasting longer" when masturbating is normal. Sometimes this quickness leads to premature ejaculation, defined as "ejaculating sooner than he or his partner would like." Treatment is usually behavioral, including the "pause-squeeze" technique, topical anesthetics, oral medications, counseling.
