Gel or cream to prevent STDs of oral sex?

[attnetwork]

I'm a male in his 30's no STDs. and I have been meeting with woman more frequently recently, always condom-protected. But sometimes the mood is killed by using condom when receiving oral, also I'm not giving oral sex for fear of STDs.
    
I'm planning to use viblok, to reduce the risk of getting STDs because there some clinical that says that it could help to reduce viral load in skin. I would like to have tenofivir-based cream also, but I can't find any way to buy it. Is there any options of gel/cream for oral sex?

Greetings
There are no such options in terms of protection.
No matter what you put on your penis (unless it is a condom) it is ineffective against STDs.
Oral sex poses little risk, but no cream, gel or ointment can make it safer, it just doesn't work out.

Exactly this. Only methods for stopping STIS are:

Abstaining from sexual practice
Using condoms.

I need to add, as a woman, to not use any of these things without first talking to the woman? You have no idea if she's allergic, or has really sensitive skin, and the side effects for her could be awful.

Vilock isn't meant to be used ON the vagina, but on the bikini line. It has not been studied for safety in people with hsv2.

Also, as a woman WITH hsv2, if you are scared of us, don't have sex with us. I'd much rather you ask me about my STI history than start using things on your genitals or mine that could cause reactions.

Also - there's this - https://academic.oup.com/jid/article/212/12/1949/2911923

If you have a partner with hsv, ask them to take Valtrex - it's far more effective.

If you are having casual sex, you don't get a chance to ask for this.
