Any ideas against 5.Bc4... on Bishop's opening

[jaisol]

1.e4 e5
2.Bc4 Nf6
3.d3 b5
4.Bxb5 c6
5.Bc4

I was expecting for 5.Ba4 :-), not 5.Bc4 which is sligthly better I think now than 5.Ba4...just beginning and here ends the theory for me...

any refutation against 5.Bc4 ?

[ChessTeacher]

I haven't much experience with the 3..b5 move and it looks suspicious to me, but I think that when playing white I even prefer 5.Ba4 above 5.Bc4.
Is it your intention to play 5...Qa5+ or 5...d5 or ...?
