Hi Thank you for asking HCM I have gone through your query.The fluid that leak while talking to your girl friend is precum or pre-ejaculatory fluid and it not semen. That is possibility of some sperms in that.It is usually present in healthy males when they get excited so you don t need to be worried about that. If you get a premature ejaculation that is when you ejaculate semen before intercourse or suddenly when you do intercourse then you can try following.You can do squeeze and stop technique.You can stimulate your partner before getting yourself stimulated.You can deviate your thought to something nonsexual when you about to near ejaculation.You can put on a condom or condom with anesthetic which will decrease the excessive stimulation on penis and there by prevent premature ejaculation.If all these not helping then you can approach a psychiatrist for behavioral therapy and medicinal management like anti depressants.SSRIs like Paroxetine as well as clomipramine give good results in many.Dapoxetine which is a short acting SSRI can be used in need also.Hope this may help you. Let me know if you have any further query.
