Yes. Hormones are flying around and you don't know your sexuality properly.
for me it is but i have my peroid
Yes it is normal. Some people want to have sex and others don't. By the way, it is really good that you are a virgin.
It depends on how they do it. Rarely do lesbians have penises, because to be lesbian you have to be female. Sometimes they have sex with dildos, but no it is not exactly the same.
it means you want to have sex with them. if its opposite sex. same sex means its disrespectful
Because they want to look normal. or they are faking bisexuality to begin with. or only the ones you see marry the opposite sex. There are a great deal of bisexuals who have married (or have tried to marry) the same sex.
yeah if you are a normal person
Screaming or no screaming, w/e they want to do is normal.
It is not only normal, it is refreshingly healthy.
yes you can
sex make you want to sleep or rest for a few minutes, that's normal
if you are 35 and are not turned on by anything or if you are a virgin or never have sex or you have had sex and you didn't like it then you could be A-sexual i think this means you have little or no sex drive. Some people who are A-sexual may want a relationship and no sex or they don't want anything you also get A-sexuals who want relationships with the same gender and still not want to have sex. I not a doctor so i can't say that your 'this' or 'that' but i can say that if your not sure about the information I've given you then i'd go and see a doctor. :) http://en.wikipedia.org/wiki/Asexuality
Yes, it is completely normal for any individual to not want or be interested in sex at any age, including 21. Each person's level of sexual desire and interest can vary, and it's important to respect and prioritize their personal boundaries and choices.
