<bot>: Hi, Your erectile dysfunction could be due to psychological issues or performance anxiety for the first time. The erectile dysfunction problem is very rare at such a young age.  However still you can investigate with serum testosterone estimation and get checked your sugar level and measure blood pressure.  You can practice more foreplay for getting a hard penis and then only try to insert it in vagina. You can Consult sexologist for counseling.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
