There are two types of brachy, used for two very different diagnosis.
LDR, or seed, or permanent brachytherapy tends to be used on T2 low risk diagnosis.
You didn't give enough details of your diagnosis, but you might be T2 low risk.
HDR, or temporary brachytherapy is currently popular with External Beam Radiotherapy for high risk cases,
Gleason 8 or above, or T3, or PSA >= 20.
For ED, you need to know if you are eligible for nerve sparing with a prostatectomy. It's a risk with just about every treatment, but the risk varies. With prostatectomy, you will lose erections afterwards, but if you have nerve sparing, around 3 in 5 people get it back between 6 months and 2 years later. For Radiotherapy, it rarely has any instant impact, but around perhaps 2 in 5 cases, erections are lost slowly between 2 and 7 years later.
One other thing I would warn you about. When diagnosed on the NHS, you come under a multi-disciplinary team (MDT) consisting of urologists, oncologists, radiologists, etc (there were 30 clinicians in my MDT). They reach an agreement on what treatment is (or treatment choices are) best for you, and this stops one consultant just pushing their on procedure. When diagnosed privately, many people only ever see one consultant, and get pushed into doing what their particular procedure is. Do make sure you are getting good advice about a range of treatments.
