What is twitter used for? my boyfriend?

[Wokki]

I dont have it but my boyfriend went on it at my house last night and he is following lots of naked women and I am a bit annoyed as there was so many and they are all page 3 or from porn websites etc They were all really skinny with fake boobs and blonde. (Women he tells me he is not attracted to)

I'm just a bit annoyed as I didnt think he was this kind of guy and we have been together 4 years.
He is 28 so thought he would of grown out of this too.

When I asked him about it he just got mad and denied it.

I understand he finds other women attractive but why do this?

I feel angry
