Почему у него не возникает эрекции со мной?

Considering the circumstances, it is improbable that your girlfriend could become pregnant if there was no ejaculation. Nevertheless, it is good to realize that any genital contact has some risk involved. Therefore, if she starts experiencing any unusual signs like missing her periods or having abnormal bleeding; I advise you to go for a pregnancy test so that you can be sure about everything.

Masturbation is a normal and positive practice. It is not a problem and does not need treatment. The healing process in your body occurs naturally and medicine helps to maintain the hormonal balance. Masturbation will not be a hindrance to your marriage. The tear of the hymen may be caused by other reasons, for instance, accidents during sports, which are not related to masturbation. However, the hymen should heal naturally. 

Frequent se­lf-pleasure could be causing tightne­ss in your private area. This occurs when muscle­s get overworked. Te­lltale signs are pain or discomfort during ere­ctions. Cut back on activities for muscles to recove­r. Drink lots of water, and gently stretch too. 

First of all, never use two condoms at once because they will rub against each other and could break, which would increase the chances of HIV, not decrease them like some believe. Also, did you know that there is still a possibility of getting HIV even if only one condom is used? Therefore I recommend asking a doctor about PEP (post-exposure prophylaxis) drugs in case one had sex without protection. 

I think you might have premature ejaculation. This means coming quickly when you’re touched sexually. It’s common and can be because of stress, nervousness, or inexperience. Try to be relaxed about it and talk to your partner. 

When ejaculation appears before the due time, it's mostly known as premature ejaculation. This means that ejaculation takes place earlier than you or your partner would like, in the course of sexual intercourse. It is common and is often the result of stress, anxiety, or relationship issues. Make an effort to practice techniques like the start-stop method or deep breathing during sex. In some cases, therapy might be helpful. 

Having sexual intercourse with an HIV-infected partner without condoms is risky and may result in HIV infection. If you have had sexual intercourse with a sex worker and the condom has torn, you should test for HIV as well as other STIs as soon as possible. 

A "non-reactive" result indicates that the test did not detect HIV antibodies or antigens in your blood at the time of testing. And you have consistently received non-reactive results over a span of a few months. However, for definitive advice regarding testing intervals and your specific situation, it's essential to consult a professional who specializes in sexual health or infectious disease

Even though you have the condom on, some STIs can still be transmitted, such as herpes or genital warts. Signs could be pain during urination, unusual discharge from the vagina or penis, sores, lumps, or itching around the genital area. See a doctor for testing if any of these symptoms show up. 

Considering the chance of getting HIV from having unprotected sex is important. For instance, the symptoms such as tiredness, flulike symptoms, white coated tongue as well as lie bumps which you explained could mean several things and not necessarily that someone has been infected with this virus. It’s good that you intend to go for testing; that way one can never be too sure unless they get checked for it. 

Typically, ceftriaxone is effective, but it's essential to complete the entire prescribed course. Please visit your healthcare provider or a specialist in sexually transmitted infections to ensure your treatment is appropriate and complete.
