Maintaining penile erections during sex depends on focus and concentration in act. Any mind diversion/deviation/distractions lead to loosening of already attained erections.
In addition, in some people due to defective valves in veins venous leakage happens causing loss of erections. Penile Doppler test will confirm/rule out such possibility.
In former case, you better consult Psychiatrist who is trained in Sexual Medicine can help you.
