Robin,
Even though I'm a man, I totally agree with what the ladies here have said to you; This should never be considered a Taboo topic, as I feel it's a perfectly normal thing, for both men and women to feel!
And I don't think there's anything wrong, with men and women taking care of their own sexual needs and urges, by themselves, either!
The only thing I would advise, is, just like the ladies have said: Don't rush into anything, involving another man; no matter how kind and genuine they appear to be!! Because, sadly, most of us men are sex-driven, and are usually out to get that: and only that! If you know what I mean!! And the last thing you need is to be either heartbroken, or caught up in a relationship or situation that only complicates your life, and which you really probably don't need: Especially at this stage, when you're still grieving!!
Anyway, I hope this helps, at least a little bit?!
Kindest Regards, always,
littlebro
