Hello,
Thanks for the query.
Brief answer...There is zero risk of STD in you.
Detailed answer.....
To get an STD,one has to have an exchange of body fluids by way of sexual contacts like oral sex,anal sex or vaginal sex.Just by touching a vagina and he touching your penis,doesn't result in STD.
Just relax and forget about it,as ther is no fear of any STD.
I hope it helps however you may revert to me for any further query.
Best of luck
Thanks
