Thank you for your consult at DoctorSpring.com.
One can certainly counteract the infections from sex toys and the touch of person's vagina or anus. However, as you have remarked that the lady appeared to be clean and hence you should not worry about them.
However, you shall certainly merit evaluation if you develop any symptoms.
Take care. Please feel free to discuss further.
