Bottom line is that the condom broke. You need to test.
Having, or not having an orgasm has nothing to do with contracting the virus.

You had a risk due to condom failure, as you were advised already. When a condom breaks during penetration, exposure time or number of strokes does not matter.
The single most severe disadvantage associated with a condom is, it provides 100% protection against HIV, only if it does not fail, but once it does, a totally protected sex turns otherwise all of a sudden. Therefore correct use of the condom is very important because prime cause of failure is the incorrect use.
