Condom questions. Non latex condoms.

I got some of these the last time I went past Terrence Higgins Trust. . Didn't know such things existed as I've never seen them in the shops (not that I was looking as I don't get sexed that often).
The Pasante 'Unique' ones come in a neat credit card sized holder, which is safe to keep in wallets, unlike regular latex condom packets which tear after a while. I've some condom cases which were distributed at an event I was at were donated by Gaydar chat but it's easier to forget the condom case than my wallet going by my experience several weeks ago.

I've a latex allergy  - my hands developed a rash after using non-powder gloves ( I asked ARCO specifically for non latex gloves) which spread to my feet through scratching them - combined they looked like a secondary syph lesions.
Though I only suspected a latex rash the nurse doing my bloods the other day had put on a plaster noticed another plaster from a medical a couple of weeks ago and took it off to reveal a rash. He asked if I had a latex allergy, I didn't realise there was latex in plasters. He took off the one he had put on and the area was inflamed in a plaster shape already after a minute.

Thing is I can't recall ever having had a reaction from latex condoms, are they hypo-allergenic or something? I've read of 'low protein' gloves, are latex condoms low protein or is the protein in the powder in gloves?

I guess the non-latex are as good as latex condoms? I don't do anal so lubricants aren't an issue.

Should I bother with dental dams for giving cunnilingus? Guess though HIV is extremely low risk Gon, Syph, Chlamydia, thrush are hazards.

I see you haven't learned a damn thing while being on the forum. Geesh. I see no reason for anyone to waste anymore time with you.

There is no need to slate me for asking a genuine question.
You could have just not answered.

No one has discussed non latex condoms or the allergens in latex while I have been on the forum.
I haven't opened the packet because I haven't had sex, they are expensive and difficult to find so I'm not going to waste one seeing how tough it is.
The guy at THT said they were thinner and they go on differently so I would like to know if there is an increased risk of them failing?
I'm no expert in polymers.

Also we have, in general, discussed HIV on this forum not other STIs. So I will address that question to the STI forum in my own good time.

The header does state
"...have questions about the effectiveness of condoms or risks associated with specific sexual practices, this is the site for you"

so my questions are valid.

I opened one of the non-latex packets the other night to see how strong the material is.
Result - I'm not inspired with confidence! I don't think any partner would be either.
Think I'll stick to the latex ones as they are explicitly recommended in literature from health authorities.

So are polypropylene condoms. I really don't care that you are allergic to latex condoms as long as you use them and protect your partners.
