How can infection spread through sperm in anal sex?

Question

Hi doctor,

I am totally new to sexual life and I read a lot about it but have some concerns. First of all my questions would be about gay sex (male with male). Secondly, in my questions I am assuming that no condoms or so protection used.

1. Assume that both parties do not have any disease and one of the cum with huge load inside the ass of other person. Does male semen create or causes any major or minor disease by its own when it is is contacting male ass.

2. Similar to the first question, what if the cum load (semen) was in the mouth. Does male semen create or causes any major or minor disease by its own when contracting mouth.

3. What if 2 male cum at the same time inside the ass of one person does the difference of DNAs in the two different semen cause/create/make any diseases?

4. Why always doctors talk about transmitted diseases but not generated/created/made diseases.

When I ask about sex safety I feel like I am getting unrelated answers because I am surely not considering to have sex with someone who is not tested but people always seem to talk about diseases that are transmitted. So please help me to answer based on the case scenario give.

Hi,

Welcome to icliniq.com.

I have read your query. As per your scenario the answer is no. Semen in itself cannot harm rectal mucosa or oral mucosa or make a new disease. Only if your partner/s has a disease that is transmitted via body fluids, only then you can get it. Same scenario with two males, their DNAs will not react together to make a disease. But, that said anal fissures can result from lack of lubrication, improper dilatation and improper penetration. However, you end your query by saying you and your partner are planning on getting tested and want to know tests: For this it is better that you both undergo the full panel of STDs and also get tested for Hep B/C, etc.
