I'm not a sexual but me and friends were playing dates my friend dared me to peck another friend i actually feel physically sick what could this be?

Consult therapist: Not quite clear what you mean by "not a sexual" in terms of your orientation. Variety of possibilities from simply being a little repulsed by the idea of intimate contact which may be normal to perhaps some underlying deeper emotional reaction that is causing physical symptoms. Would be worth discussion with a counsellor or psychologist to explore this and work out if there are any issues.
