just go visit doc say u got erection problem la, buat apa malu malu, sendiri suffer only

have u tried exercise?

How old are u?

Need to do strength training apart from just cardio exercise like jogging.

Build muscle will increase testosterone which decreases or lack of as u getting old.

+1

studies show lift weight, can increase testosterone level, squats also help

jogging only for cardio and weight loss

Not sure how to recommend as i also dun haf muscle building plan pun.

But currently i'm using dumbbell (Adjustable Dumbbell Set) every weekend for 30mins then everyday do pushup around 50-60 times per set everyday. Usually do 1 set or sometimes max 2 sets coz lazy.

Cardio exercise also do minimum 30mins every weekend.

Ok la not bad the outcome. Didi more tegang every morning and can last longer then previous when piaping.

Need to jaga makan also eat less carbo and eat more protein based food.

plz elaborate your performance.. at first your thing is hard but after a few stroke it got soften?

40 is still young and too early. Any kind of disease? Diabetes? You should consult specialist.

Better discontinue. Can harm your kidneys in the long run.

Calisthenic aka body weight exercise

Google it or search it in youtube for beginner

basically is push up , pull up and squat

almost zero cost or cheapest way to build muscle

at the end of the day is about your commitment and discipline, without these two what godlike exercise also no use.
