Hi doc i am a boy of 17 years old and i have had ED for a good year now and i have thought of all the possibilities, and one of the conclusions i have come to is can having a laptop on your lap everyday for a good while have an effect on erections? I can get an erection but it is not as strong as it should be and will become flacid in seconds.My problem is very embarrassing and its taking away my sexual youth.
Hello, The laptop usage and putting over thigh has no correlation with erectile dysfunction. Usually after a few seconds or minutes of erection if sexual stimuli decrease than erection lost.  But if you feel erection is not proper in this few days than you have to consult a psychiatrist for detailed evaluation. The excess stress, obesity, spinal problem, prostatic problem, smoking etc. some causes. If needed your doctor will suggest you investigate with Doppler penile angiography as well.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
