Interesting thread... IMO the biggest issue with HIV is lack of education. People still totally freak out if they find out someone is HIV+.
I worked in healthcare for many years. The facility I worked at had one the first Aids Hospice units in the USA.
This was early 90's. If you were HIV+ which developed into AIDS, you were toast.
The staff of the unit were great , but many of the other hospital staff were downright ignorant and cruel. I will never forget those times.
Getting back to the OP.... If I had strong feelings , I could have a relationship including sex with an HIV+ partner. Obviously there would have to be guidelines that we both agreed to .
