Hi,
Thanks for your query.
This does not sound like HIV at all. HIV does not spread in the manner you describe. Deep kissing can result into HIV if there is a gum disease or bleeding in mouth from sores. If there were any genital ulcers from chanroid, herpes, syphilis or other sexually transmitted infection, it enhances the chances of getting affected by HIV.
Syphilis infection spreads through intact skin frottage (rubbing of sexual organs together) can spread syphilis but not HIV.
From next time onwards, try to practice safe sex with condoms all the times. Have yourself screened for HIV and syphilis and keep healthy.
