I think he can handle this with his gf. He accepted the condoms, he can explain---not sure why she would be so upset since it is a good idea anyway since bcp do not prevent sexually transmitted diseases. (& since they are not likely first to each other, it is like having sex, in an indirect way, with all those who have gone before...& some do not show up right away (eg herpes, hpv...) and some do not cause many symptoms in men (chlamydia....others)
