Oh I'm sure you can. Particularly through IVF, though certainly IUI should work also. I don't think your hymen (which would be the only difference between one who's done the bd and those who've not) has anything to do with becoming pregnant.
yes im pretty sure. i know a couple who have been in a same sex relationship for 17 years since there teens and they are now ttc via ivf. no luck as yet as both times they were succesful but it resulted in m/c. from what i can see neither of them have been with a man previously ( presumably as theyve been together since they were young).
im not an expert though but I would say yes.
best of luck to you
