Welcome to the HIV forum.
You cannot catch HIV by hand-genital contact and oral sex is virtually zero risk -- some experts believe it to be truly zero.
As for the thrush, you don't say how that was diagnosed. Thrush is a yeast infection. If all you had was a white coated tongue or maybe white spots in the mouth, not professionally diagnosed as thrush, then I doubt that's what you had. And even if you had oral thrush, that is a sign of advanced HIV infection (i.e., overt AIDS), not of early HIV infection. And a brief illness with one day of fever is not consistent with HIV as the cause. A viral respiratory infection or strep sounds more likely than either thrush or HIV as the cause of your symptoms.
See a health care provider if you remain concerned about this. But there is nothing in your story that makes me worried about a new HIV infection.
Good luck-- HHH, MD
Thanks for the reply.
The thrush I had was on my penis, it cleared up after about a week. Hence why I thought I may have had penatritive sex and why I am now concerned.
Thrush is an unlikely cause of penile rash, although it is possible. It also requires professional diagnosis, but in any case penile fungal infections do not suggest HIV.
Some aspects of your wording suggest you may be in the UK. ("Thrush" is an uncommon word for yeast infections in North America.) If so, you can get high quality evaluation and advice at a NHS genitourinary medicine (GUM) clinic.
