At 32 years, 102 kg and 5'8", your reported erect length of 3.5â4 inches (8.9â10.2 cm) is below the average erect length of about 13.1 cm (5.2 inches), but it cannot be diagnosed as micropenis from erect length alone. The medically appropriate measurement is stretched penile length (SPL), measured from the pubic bone/penopubic junction to the tip of the glans. Micropenis is defined using an SPL more than 2.5 standard deviations below the population mean.
Your weight is also relevant. In men with obesity, some of the penile shaft can become concealed by surrounding suprapubic tissue, producing an adult acquired/buried appearance despite a normally developed penis. The EAU specifically recommends genital examination in men with BMI >30 who are concerned about penile size.
Next Steps
Before considering marriage or any enlargement treatment, I would recommend one examination with standardized SPL measurement. If the SPL is normal, further testing for penis size is generally unnecessary. If you have normal erections and no other genital abnormality, your reported size alone does not mean that intercourse or married life will be unsuccessful.

Health Tips
Please don't let this measurement alone become a reason to avoid marriage. Penile length is not the same thing as sexual satisfaction. Erection quality, arousal, communication, stimulation and intimacy are much more important factors in a couple's sexual relationship. Also, don't compare yourself with pornography or internet images. Given your weight, gradual weight reduction and regular exercise may improve both the visible appearance of the penis and overall sexual health if some of the shaft is concealed by suprapubic fat. Most importantly, avoid unregulated penis-enlargement injections, pills, weights or aggressive stretching, which can cause permanent injury. Thank you
