You were never at risk. Your condom did not fail and remained intact throughout. Kissing and unprotected receptive oral has nothing to do with HIV transmission.
Though you don't need any testing, but you may do so, only to lay your worries to rest permanently. It is good time for you to get yourself tested and collect a "negative" report, very positively.
6 months ago is long enough, get tested and 100% negative.
You arent gonna get hiv from kissing or oral sex. Plus your exposures were 6 months ago, symptoms dont show up 6 months after exposure they show up within a few weeks.
