You've been seriously over tested. And you were at little or no risk of HIV: there have been few or no reported cases of HIV transmitted mouth to penis, so you really didn't need testing. The AgAb (4th generation) HIV blood tests are conclusive at 6 weeks and beyond. Your tests after 46 days were unnecessary even if you had been at significant risk.
