Why would anyone give you grief about being sexual?
Both are normal - millions of people find the pill is reliable enough for them but plenty of women like using condoms as well. That can be because of the extra protection against pregnancy, because condoms protect against STIs, or because they don't like having semen inside them.
If you're this worried, you can either use condoms too or consider something like the implant which is staggeringly reliable as a method of contraception.
