Edited sentence: Another suggestion offered by evolutionary biologists to explain premature ejaculation in young or inexperienced men is that early ejaculation maximizes the chances of impregnating a female if sex is infrequent, furtive, or rushed.For example, males who are lower in the social hierarchy, especially among troupe primates such as chimpanzees, sexual access to females can be usually limited to dominant males; therefore, male chimpanzees taking covert advantage of rare copulatory opportunities will have greater likelihood of impregnating a female and passing on his genes if he achieves climax quickly.In a less pathological context, premature ejaculation could also be caused simply by extreme arousal.Interpersonal dynamics strongly contribute to sexual function, and premature ejaculation can be caused by a lack of communication between partners, hurt feelings, or unresolved conflicts that interfere with the ability to achieve emotional intimacy.Neurological premature ejaculation can also lead to other forms of sexual dysfunction, or intensify the existing problem, by creating performance anxiety.Psychological factors commonly contribute to premature ejaculation.The body may interpret infrequent sex as evidence of scarcity and therefore attempt to utilize that potentially limited opportunity by passing genes as quickly as possible.While men sometimes underestimate the relationship between sexual performance and emotional well-being, premature ejaculation can be caused by temporary depression, stress over financial matters, unrealistic expectations about performance, a history of sexual repression, or an overall lack of confidence
