###Human: How can I strengthen penis and cure premature ejaculation? ###Assistant: Hi. Masturbation per se does not cause any sexual problem in the future life, so do not worry excessively about it. However, to manage premature ejaculation you can learn about the start-stop technique or squeeze technique. There are medications available for this purpose like Dapoxetine 30 mg one hour prior to sexual activity. Also, get yourself investigated to rule out medical conditions such as thyroid dysfunction or diabetes hypertension, etc. Also, try Keigal exercise to strengthen your pelvic floor muscles.
