No it was not a risk for HIV transmission.
Urethral sounding equipment has been outside the human body exposed to the environment and as for the BJ nobody has ever been infected from receiving a BJ and you will not be a first in history. Nothing you mentioned was unique and it was not a risk.
With regards to the other site, I don't care or comment on what others say .
Here's what you need to know in order to avoid hiv infection:
You need to be using condoms for anal or vaginal intercourse, every time, no exceptions. As you are sexually active, it is highly recommended that you get a full sexual health check-up / screening at least annually including but not limited to hiv testing.
Remember that some sexual practices which may be described as Ďsafeí in terms of HIV transmission might still pose a risk for transmission of other STI's. So please do get fully tested regularly for all STI's including HIV and more frequently if unprotected intercourse occurs. Also note that it is possible to have an STI and show no signs or symptoms and the only way of knowing is by testing.
Finally use condoms for anal or vaginal intercourse, correctly and consistently, to avoid sexually transmitted hiv infection.
