If the virus does not enter the body, can one become infected with HIV?

1.
About three to four days ago, I engaged in unprotected sexual intercourse, but I only rubbed a little on the outside before ejaculating, with just the tip of the penis entering slightly.
Is there a risk of contracting HIV from this? I have already started taking PrEP (pre-exposure prophylaxis).

2.
I have small, round, pimple-like bumps on my foreskin that are all the same size.
Could this possibly be a sexually transmitted infection?

---> There is a possibility of HIV transmission if bodily fluids from an HIV-positive person come into contact, although the risk is significantly lower than with full sexual intercourse.
2.
I have a ring of small, dot-like bumps on my foreskin that are all the same size.
Could this be a sexually transmitted infection? ---> It is possible that this is related to sebaceous issues, but if there has been unprotected sexual activity, it is still advisable to consult a physician for examination.
Wishing you good health.

More Info

When it comes to understanding the risks of HIV transmission, it's important to consider various factors, including the nature of the sexual activity, the presence of bodily fluids, and the health status of both partners involved.
1. Risk of HIV Transmission with Partial Penetration: In your case, you mentioned that during a sexual encounter, there was only partial penetration with the glans (tip) of the penis. While the risk of HIV transmission is significantly lower with partial penetration compared to full penetration, it is not zero. The primary risk factors for HIV transmission include the presence of HIV in bodily fluids (such as blood, semen, vaginal fluids, and breast milk) and the presence of open cuts or sores. If the partner you engaged with is HIV positive and there was any exchange of fluids, even minimal, there is a potential risk. However, since you are already taking PrEP (pre-exposure prophylaxis) with the medication "Genvoya," this significantly reduces your risk of acquiring HIV, provided you are adhering to the medication regimen correctly.

2. Skin Lesions on the Foreskin: The small, raised spots you describe on your foreskin could be due to a variety of causes, including but not limited to sexually transmitted infections (STIs) such as genital warts (caused by HPV), molluscum contagiosum, or other dermatological conditions. It is crucial to have these lesions evaluated by a healthcare professional, preferably a dermatologist or urologist, who can provide a proper diagnosis and treatment if necessary. Self-diagnosing can lead to unnecessary anxiety or mismanagement of a potential condition.

In summary, while the risk of HIV transmission from partial penetration is lower than that from full penetration, it is still present, especially if there are any factors that could facilitate transmission, such as the presence of HIV in the partner's fluids. The use of PrEP is a proactive measure that significantly reduces this risk. As for the skin lesions, it is advisable to seek medical attention to determine their cause and receive appropriate treatment. Regular check-ups and open communication with sexual partners about health status and safe practices are essential in managing sexual health and reducing the risk of STIs, including HIV.
