start of with a urologist.
It shouldn't hurt. You may want to consult a doctor.
Yes it is called a sex change. Consult your doctor about this.
No, there shouldn't be any problems at all.
consult your doctor, you could have an std and yeah that's a sign of infidelity
It should not be. If it is, please consult with your doctor or a clinic and describe to them what circumstances might make it so. They can help.
You should see a doctor.
depends have you had unprotected sex, it may be a STD
No problems, they aren't always straight.
If you find any changes to you penis after sex, things that weren't there before you had sex, see your doctor as you might have caught an infection such as an STD. Don't have sex with anyone else until you have seen a doctor because if it is an STD you will just spread it to more people. The pimples you describe might be completely harmless but if they have suddenly apeared after sex it is better to see a doctor and be certain what they are. If they are the result of an infection it won't go away if you just ignore it, it will only spread and get worse so the sooner you seek help the better. It is better to be safe than sorry.
If this is painful or prevents you from general use of your penis (for example, painful sex or trouble urinating), see a doctor asap. Otherwise, I would still see a doctor about it anyway, but the priority would be lower.
No, that is not normal. The foreskin is normally attached only at the base, so that it is able to slide back to expose the penis, during sex (for greater sensitivity). If it is actually attached at the tip, I would suspect that it just got stuck by some dried residue, but if it is attached by skin and not just by glue, consult a doctor.
You have the funk or crabs. Please consult your doctor or avoid sex during these times.
