Brief Answer:
Hi, Erection problem may have many causes.

Detailed Answer:
Hi dear

I admire you for positive outlook.

I understand your concern.

You can not get aroused means you don't have erection or not have a desire to do sex

If you are sexually attracted means you have sufficient desire to have a sex.

So I guess the main area of problem is not having proper erection.

Erection depend upon several factors.

1st is physical health.

Routine check up and physical health is necessary.
Basic test to rule out medical condition like Blood pressure , diabetes etc.
Penile Doppler will help you to check blood flow in penis to rule out any medical condition that affect erection.

2nd is Relationship.

free communication and mutual understanding will help
sex is mutual act. So require support of both the partners equally.
so try to do mutually and tell your problem to partner.
this will reduce your anxiety and able to erect easily.

3rd is life style
stress and busy life style make u fatigue and secondary to this it makes less desire in sex and erectile problems.

Change in life style like

Regular exercise.
Meditations.
Proper sleep.
Healthy diet.
Do pleasurable activities.
Stress free schedule and work.

All will help you to handle daily stress.

Psychological soundness is must and sun set focus method for erection is very useful. It is method to involve in a sex gradually to make you stress free.Long fore play and once you will notice good erection than only involve in sexual activities.

I prefer medicine like sildenafil , tadanafil and tetrafol plus in my selected patient. But it require proper evaluation.

So talk with your wife and discuss everything. Do not tell her to do sex with someone else.
Just concentrate every aspect that i have said.

Hope for the best.
Still have a query than feel free to ask.

Happy to help you.
Thank you.
