Minoxidil shouldn’t cause any issues in that department, in fact I believe Big Pharma are trying to patent a topical minoxidil treatment for inducing erections, after some study found it more effective than topical nitroglycerin in some cases (have a search on pubmed for the study if you’re interested). After reading about this I have of course applied it to the glans and noticed some erectile response follows some time later.
Anyway, for hair loss, the amount applied topically isn’t much and far less of that get absorbed systemically.
When first dealing with my hair loss and taking medication to combat it (finasteride was what I first started using, I now use both finasteride and minoxidil) I noticed some erectile issues, but, personally I’ve put that down to ‘psychogenic’ reasons, after all self-image accounts for a lot.
Are you on any other medications? Have you tried lowering the amount of minoxidil you use?
Make sure your diet is healthy and you’re getting all the vitamins and co-factors you need - it really can make a difference.
Studies with arginine and an anti-oxidant seem to show benefit, and many users here will attest to the benefits of arginine or citrulline. They don’t compare to PDE-5 inhibitors, but can make a difference.
I’ve noticed no issues with doing PE while on minoxidil (or the rest of the things I’m on), only benefits.
Good luck.
