yes.
good :)
It's supposed to. If not, there could be problems in the relationship.
It's bad if you can't feel cold because your body is supposed to be hot or cold. If you can't feel cold, see a doctor.
Try talking to her about how you feel. If she doesn't care then what's the point in being with her. Relationships are supposed to make you feel good.
If it is the first time for a girl it can hurt because her hymen has to break in order for the penis to fully enter the vagina. The hymen can break down on it's own before intercourse, especially if the girl is athletic. Any contact with the genitals is intended to be pleasurable. Sex should feel good for most parteners.
endorphins
good
Girl feel good :)
The good parts is that you won't have feelings and you wont be stressed out but the bad parts is that you won't know how your supposed to feel
For a guy and girl yes it is. The girl will feel a full body almost spasm and chills down your back. And you'll hear slurping sounds and feel it get wet. The guy will feel it get wet suddenly, and will experience a suction for a couple seconds, so very good.
you shouldn't have to convince her, dont try to talk her into something that she's uncomfortable with. or if shes just scared get her relaxed and tell her it'll feel good and that you wont hurt her and dont!
oh yeah. It might be akward the first time but its just great
