You need not worry about it. By practicing yoga, you can delay your time of ejaculation. There are other simpler techniques also like:1. Usage of condoms (Also there are condoms which contains endocrine, which will delay your ejaculation, and you can last long in bed, but regular use is not advisable)2. Giving pressure at the junction between your scrotum and anus with finger (even your partner can do this for you)3. Reduce anxiety and fears4. Do not think about anything else other than sex while doing sex.5. Pause for a while when you are about to ejaculate for 3 sec to 1 min. Even after trying these, if you are having PME, then you may require further consultation and tests. TC </s>
