I understand your concern.
No Ultimate V-RX is not useful as Viagra
. Both has different mechanism.
Erectile problem has many origins
1st is life stylestress
and busy life style make u fatigue
and secondary to this it makes less desire in sex and erectile problems
2nd is relationship
free communicative and mutual understanding will help
sex is mutual act
so try to do mutually and tell your problem to partner
this will reduce your anxiety
and able to erect easily
so stress free lifestyle and mutual communication will help
third is physical health
routine check up and fit physical health is necessary
psychological soundness is must.So treatment of underlying stress and anxiety will give more response.
medicines like sildenafil(Viagra),, tadanafil, tetrafol
Do take advise from doctors.
Still have a query then feel free to ask.
