Hi thanks for your question
You’re experiencing low back pain
along with tingling sensation
radiating along your right leg and lack of erection.
These symptoms are suggestive of prolapsed intervertbral disc.
The prolapsed disc can press on genital nerves leading to importance.( lack of erection)
Consultation with a physician is encouraged to know wether you prolapsed disc or not
You may need MRI
spine to establish cause of your back pain and treatment accordingly.
Hope this answers your question.
