Is it normal that my boyfriend thinks that i should prefer him first?

It depends on teh situation. Does he not let you see your friends at all? If so, then it could be a problem, but if you are not spending a lot of time with him but a lot of time with your friends, I can understand that upsetting him.

sounds like a clingy jealous boyfriend to me. i'd say you should voice your concerns with him and let him know that he is being clingy and jealous and those qualities are unattractive. and explain to him that since you are such a great person, that he needs to share you with other people and not be so selfish, so that you can bless other people's lives as well as his.

Focus on your homework.

People have different concepts and ideas about love, friendship, relationships etc.
Personally, to me love and long term relationship with my partner with whom I share sexual and emotional intimacy is more important than friendship or other forms of relationships, so I prefer my partner to my friends or other people, so naturally it would make me feel frustrated if I preferred her as my number one in my hierarchy and she would take me just as number 3 or 15... But fortunately I and my partner are similar in this respect but I think it is not so common nowadays when people have all kinds of priorities except for their partners. It is not right or wrong, good or bad, but it is great if two partners share the same hierarchy of priorities.

Sounds like ur dating a female no offence.

Why is it that this is even a problem? Are you ditching your boyfriend for your friend? Are you ditching your friend for your boyfriend? Does your boyfriend have a problem whenever you hang out with a friend?

All the time is bad. Some of the time is okay. It's all up to you to decide how much time is enough and how much time you'll spend with each person.

Unless it's to an extreme extent, you should generally favor your boyfriend over other friends. Getting blown off by your partner can often times be seen as personal especially at the beginning of a relationship. Voice your opinion. If you can't even talk about the subject then you honestly should not be together.

You should, lovers first, friends second.

If it disturbs you enough to ask then something is not quite right for you.

Awe. I wish i had a boyfriend like that.

Of course you should prefer him first for sex that is what he prefers you for.

I hope he is your first choice for sex instead of other people. If you are talking about going out and having fun, you will lose this boyfriend by him just leaving or him picking his friends first also and you two never spending time.
