How long is your cycle, what are the doses, how is it spread out? Are you afraid of needles, hence orals only? I am assuming since you are using winny and Anavar you're not looking to blow up, but looking more for strength/increase LBM/improving body composition with little bloating. Well test or 4AD will add a "Little bloat". 4AD hardly bloated me at all. Test prop could work well also, but you should shoot minimum EOD.
I don't think you'll have a problem with sex drive, but if your worried, I'd add topical 4AD (worked very well for me) or Proviron. Proviron at 50-100mg ED is pretty much like taking viagra, except your body will harden up too. We're talking perma wood bro. Proviron is hard on the prostate though, so you may want to factor that in as well.
Hope that helps
