Hi, you have mentioned your penis size to be 3.5 inches so that is ok. You need at least 2.5 inches of penis size for normal sexual activity. For ejaculation time, you need to relax and consult a psychosexual therapist for some relaxation techniques and few medications which can prolong your ejaculation time.

Hello thanks for asking from HCM for your health related queries

I can understand your problem and you have two main issues related to sexual functions.

One major problem is of Premature ejaculation. This is a distressing problem. In most cases underlying anxiety and poor knowledge of sexual functioning are the main reasons for early ejaculation. So to increase time you have to reduce anxiety by relaxation exercises. Try to distract yourself during intercourse. Some times pelvic muscle strengthening exercises like Kegel's Exercises, Start-stop technique by Master's and Johnson's also helps to delay ejaculation. You can take help of google or a good psycho-sexologist to learn details of these methods. If time doesn't improve with these modalities then medicines like SSRIs can be used. Dapoxetine is a SSRI drug and can be used on SOS basis to delay ejaculation. Consult a psychiatrist for prescription of this drug.

Regarding the size as per my opinion size doesn't maters in sexual intercourse and if you are getting good erections then there is no problem. There are no specific medicines available that increase penis size but some exercises like JELQING (milking like exercise for semi-erected penis) can help to improve the size to some extent if practiced properly. You can consult a good psychiatrist for help.

Thanks, try to remain relaxed and don't believe on psycho-sexual beliefs.

Take care
