I kissed a guy today and I have a little wound I bit myself 4 days ago he didn't bleed or either did I should I get checked for hiv? No blood :)

Unlikely. There is not a high likelihood of contracting HIV from a kiss without frank blood being seen/tasted. However, if you engage in any intimate behaviors or are otherwise exposed to other people's body fluids, talk to your pcp about getting tested. Stay safe.
