Possible guinea pig bullying

Question
Just over a month ago I bought two male guinea pigs (called Milton and Murray), both about 8 weeks old. Milton is already much larger than Murray, and often tries to have sex with him, even though Murray doesn't seem very happy about this. Murray never stops squeaking, and because he's a bit smaller and much jumpier, I'm worried Milton may be bullying him. But I don't want to separate them as I understand guinea pigs are social animals so they might be lonely, and also, I honestly don't have the space or money for another cage and run. Also, when I do handle Murray separately, he seems very anxious and restless until I reunite him with Milton. Really I just want to know if they're happy and normal, and if there's anything I should be doing that might make them get on better. Thanks for your help.

Answer
well the mounting is a dominence thing rather than sexual, he is not trying to hve sex so much as expressing his dominence over the younger pig. it is etter to keep them together, to make sure there is no bullying it is usually a good diea to have two food bowls and water bottles, if you can spend an hour one day watching them, especially around a feed. if murray seems confident enough to have a drink or eat something and milton does not get aggressive with him then you have nothing to worry about. if however he does then you will have to re-bond them, if so then you can always ask me or pat the other expert on bondng methods, but nine times out of ten in situations like yours all is already fine and honky dory.

best of luck.
