No it's not normal. Your husband just has messed up testicles.
Yes it is normal. Before I got pregnant every period I had my breat would hurt.
Yes.
Probably not. The husband would just have to go check in himself.
i want to know how to prepare tender
If you are just in the room or bed with the man when he ejaculates the possibility of pregnancy is 0%. The only way that a pregnancy would be possible would be if he ejaculated on your vagina. Even then the likelihood is exceedingly low.
It would wise to keep that information to yourself unless you are considering ending the marriage as the husband or wife would eventually find out. Why people would marry when they are not in love is a puzzle to most normal people.
It would be better to say 'cook until tender'
If he's much younger than your husband it might just be a nickname. : Typically only two types of people call a man "daddy". The man's children, or the man's wife or girlfriend. You do not say if your husband's friend is a woman or man. If a woman, then this could well be normal, but that would assume a romantic relationship. If the friend is male, than this would not generally be regarded as normal. Bear in mind, it may well be that there is that same romantic relationship, and that is widely viewed as "natural"...but it is not widely viewed as "normal", as it is the exception. There is a last possibility, which is the best one. It may be that your husband's friend simply has a private in-joke with him. And calls him "daddy" in a teasing fashion. This would still not be thought of as "normal", but would probably be better for you. Asking your husband is your next step. A simple, "Hey, honey, why does your buddy Vern call you 'daddy'?" would suffice. If it's innocent, you'll hear a funny story. If he's defensive, then you may wish to reevaluate your relationship, and practice safe sex in the meanwhile.
Detol kills 99.9% of bacteria, so I would go with that.
Government determines tender & they would have to back them up if so declared.
A tender would be a boat that serves and supplies a larger ship (or sub) .
Sverige is Swedish for Sweden. Swedish coins would be legal tender in Sweden.
