No. Not at all. Sex is traditionally related to marriage, but
that has changed, we all know that. BGR, however, does not relate
to sex. Some people uses it as an excuse to ask for sex from his /
her partner, saying "You are my BF / GF, so you must have sex with
me." That is bullshit.
You do not have to consent to sex under pressure. If you don't want
to have sex, tell your partner. If your partner continues to put
pressure on you, please dump him / her. He / she only wants your
body and not you.
