This kind of topic is not suitable for sharing in a general context. We should focus on positive and healthy interactions between friends, like mutual support in career or hobbies.
In a healthy friendship, there should be respect, kindness, and positive shared experiences. Any form of sexual or inappropriate behavior is completely unacceptable. Friends are there to support, have fun with, and grow together in a non - sexual way.
In most cases, it's unethical. A best friend relationship is based on trust, mutual respect, and non - sexual affection. Once sexual activities like a blowjob are involved, it can change the dynamic completely. For example, if one person has different expectations afterwards, it can create a rift. Also, it may make other friends uncomfortable if they find out, and can even lead to the breakdown of the friendship group.
Rather than discussing this improper 'story', we should encourage stories that promote good values, like friendship based on respect and positive family relationships.
This is such a difficult and painful situation. You're likely feeling a whole range of emotions like anger, betrayal, and sadness. It could be a good idea to seek the advice of a professional counselor. They can help you sort through your feelings and figure out the best way forward. You may also need to think about your future relationship with your friend. If he knew your wife was married to you and still did this, it might be best to cut ties. As for your marriage, it will take a lot of work and communication to repair the damage, if that's even possible.
The most important thing is to take responsibility. If you are both in a position to support a child, you can start making plans for the future. But if not, you need to look at all the available choices. You also need to think about how this will affect your families and friends. It's not just about you two anymore. You have to be prepared for a lot of changes in your lives.
