Hello and welcome to HCM
The type and character of bumps that you have mentioned (itchy, no pus and no sores0 strongly favour Herpes simplex
You have mentioned that you have got PAP smear
done. Wait for the report as subtle changes caused by herpes simplex are even picked up by PAP smear.
If the problem is recurrent then consulty you physician/ gynaecologists for anti-viral therapy
Till the time you are having this problem, it is better to abstain from sex as it is a communicable disease. Once you start your treatment, your partner should also take the treatment otherwise it may recurr.
Thanks and take care
